The ADIS16375 iSensor® is a complete inertial system that includes a triaxis gyroscope and triaxis accelerometer. Each sensor in the ADIS16375 combines industry-leading iMEMS® technology with signal conditioning that optimizes dynamic performance. The factory calibration characterizes each sensor for sensitivity, bias, alignment, and linear acceleration (gyro bias). As a result, each sensor has its own dynamic compensation formulas that provide accurate sensor measurements over a temperature range of −40°C to +105°C.
The ADIS16375 provides a simple, cost-effective method for integrating accurate, multiaxis, inertial sensing into industrial systems, especially when compared with the complexity and investment associated with discrete designs. All necessary motion testing and calibration are part of the production process at the factory, greatly reducing system integration time. The SPI port typically connects to a compatible port on an embedded processor, using the connection diagram below. The four SPI signals facilitate synchronous, serial data communication. Connect RST to a digital I/O line for remote reset control or leave it open for normal operation. The factory default configuration provides users with a data-ready signal on the DIO2 pin, which pulses high when new data is available in the output data registers.
The ADIS16IMU1/PCBZ provides a simple method for connecting an existing processor system to the ADIS16375BMLZ. Click on one of the following link for more information on this breakout boards.
NOTE: ADIS16375BMLZ units are sold separately.
NOTE: Order (1) ADIS16375BMLZ and (1) ADIS16IMU1/PCBZ to acquire the same materials that used to come in the ADIS16375/PCBZ, which is no longer available.
For those who would prefer to perform PC-based evaluation of the ADIS16375BMLZ, before developing their own embedded system, the EVAL-ADIS is the appropriate system to use. The remainder of this Wiki site will focus on PC-based evaluation with the EVAL-ADIS system. Here is a list of equipment required for this:
Windows XP, Vista, 7
.NET 3.5 Framework
The ADIS16375/PCBZ includes one interface PCB, 4 M2x.4x18mm machine screws and one ADIS16375AMLZ unit. The ADIS16375 is approximately 44 mm × 47 mm × 14 mm and provides a flexible connector interface that enables multiple mounting orientation options. Set the interface PCB aside, as it is not used for connecting the ADIS16375AMLZ to the EVAL-ADIS.
NOTE: Do not plug the EVAL-ADIS into the USB cable at this stage of the setup. Wait until the software installation is complete.
Place the ADIS16375 device over the “F” mounting holes and align its connector with J4 on the EVAL-ADIS.
WARNING: Make sure that the connector is in proper alignment before pressing it in. Misalignment can cause pin damage and exposure to harmful conditions.
Once the alignment with J4 is correct, gently press the top of the ADIS16375AMLZ unit down, so that its connector presses into J4. When the connector is fully seated, the ADIS16375AMLZ will rest on the EVAL-ADIS surface. The following pictures provide a reference of how this setup will look when the ADIS16375AMLZ has correct alignment with the mating connector on the EVAL-ADIS.
Select the mounting screws. The EVAL-ADIS includes a bag of M2x0.4mm machine screws, which include 4 pieces that are in lengths of 16mm and 20mm. Using the 16mm version will only allow for 2mm of penetration into the EVAL-ADIS mouting holes, while the 20mm screws will result in the screws sticking out of the bottom side of the EVAL-ADIS, when fully-secured.
Use a screwdriver to secure all four screws into the appropriate mouting holes. Note that difficulty in getting the screws to penetrate the pre-tapped holes can be an indicator of connector misalignment. The suggested torque setting for the attachment hardware is 40 inch-ounces, or 0.2825 N-m.
Set the jumper JP1 on the (EVAL-ADIS) to the +3.3V position setting for the ADIS16375AMLZ. The following picture shows JP1 in the +3.3V position

The IMU Evaluation Software is a Microsoft Windows (.NET) application that works in conjunction with the EVAL-ADIS2, in order to provide users with a PC-Based interface to most ADIS16xxx products. This platform enables observation of basic sensor functions, read/write access to all user-accessible registers, and full-rate data acquisition, which is synchronous with data production of each ADIS16xxx.
Once the IMU Evaluation software loads, you should be presented with a window similar to the image shown below.
The image below has been color-coded to illustrate the different parts of the IMU Evaluation Software. These colored sections will be referred to in the following sections.
The drop-down menus highlighted in orange list additional features and utilities that make up the core functionality of the evaluation software.
- The Devices menu provides a list of supported products. Selecting a product from this list will configure the IMU evaluation software register map. Each device has a unique register map that must be selected to ensure proper sensor operation. The green box shows the active device. In this example, the ADIS16448 is selected.
- The Register Access option calls a sub-menu that lists all user-configurable registers available from the part number selected in the “Devices” drop-down menu. It also provides read/write access to each register.
- The Data Capture option calls a sub-menu designed to enable synchronous data logging from the selected device.
- The Demos option calls a 3-D visualization tool. This feature is only supported for the ADIS16480 and ADIS16448 devices.
- The Tools option calls a sub-menu that displays USB diagnostic information.
- The About option provides more detailed software revision information.
The purple box shows the primary, inertial output registers for the selected device. These values are updated in real-time after pressing the Read button (identified by a red box).
The yellow box shows three waveform recorder windows. Each window allows for plotting the three primary sensor types (gyroscopes, accelerometers, and magnetometers [if supported]). The top subplot displays gyroscope data, the middle plot displays accelerometer data and the bottom plot displays magnetometer data. Each plot color corresponds to the colors displayed in the “Output Registers” window (highlighted in purple).
The Register Access window provides read and write access to all user-accessible registers listed in the selected device's datasheet. The image below shows a screenshot of the window.
The color-coded image below is referenced in the following section.
The purple box sorts each set of registers into a standard category. The available categories are:
- Control/Status - General sensor configuration, alarm, and metadata registers
- Output - Inertial sensor output registers
- Calibration - User offset and misc. calibration registers
The section highlighted by the red box lists all of the registers in the selected category. Click on the register name to select a register for individual read/write access.
The green box identifies the read/write control options for the current register selection.
The Update Registers in Category button (shown in an orange box above) automatically reads all of the registers shown in the selected category (red box) and updates their contents in the GUI.
The section highlighted in yellow identifies provides a means of easily calling subroutines within the connected sensor. Clicking on a button is equivalent to writing a single-bit command to the respective register.
The Save Reg Settings to File programmatically reads and saves the contents of all of the registers in the current category into a *.csv (common-delimited) file. The Load Reg Settings from File button reads a target .csv file and attempts to write the saved values back into the sensor.
The Data Capture window only supports synchronous data acquisition and logging to a file on the host PC. Data samples are only read from the sensor when the data ready pin toggles, indicating that data is valid.
The color-coded image below is referenced in the following section.
The section highlighted in red lists all of the registers that are eligible for data capture. Checking the box next to each register indicates that the specified register values should be recorded once the data stream begins.
The section highlighted in green allows for customizing the file name and location of the resultant .csv files.
The section highlighted in yellow identifies the data stream configuration options.
- Record Length - The total number of samples to be captured. A sample is defined as a single “data valid” period as signaled by the data ready pin on the sensor
- Sample Rate - The instantaneous data ready rate as measured by the evaluation board
- Capture Time - The estimated data capture time in DD:HH:MM:SS format calculated based upon the instantaneous sample rate
- Add File Header - Selects whether a header displaying the contents of each column should be appended to the beginning of the .csv file
- Use Scaled Data - Signals to the software to convert the 16-bit values read from the sensor into a sign-adjusted (two's complement) scaled number. For example, when this option is enabled, be in units of degrees/second
