CN0229 is a multichannel, flexible, analog output solution with only two analog components and meets most requirements for multichannel I/O cards, programmable logic controllers (PLCs), and distributed control systems (DCSs) applications. The circuit also contains key features for industrial applications, such as on-chip output fault detection, packet error checking (PEC) by the CRC, flexible power-up options, and ESD protection making it an ideal choice for robust industrial control systems.
The AD5750-2 is a single-channel, low cost, precision voltage/current output driver developed to meet the requirements of industrial process control applications. The voltage output range can be programmed for the standard output ranges for PLC and DCS applications: 0 V to 5 V, 0 V to 10 V, −5 V to +5 V, and −10 V to +10 V with a 20% overrange setting provided for the standard ranges. The current output, which is provided on a separate pin, can be programmed for the ranges of 4 mA to 20 mA, 0 mA to 20 mA, −20 mA to +20 mA, 0 mA to 24 mA, and −24 mA to +24 mA. The unipolar ranges have a 2% overrange setting.
The AD5686R is a quad 16-bit nanoDAC+ with rail-to-rail voltage-buffered outputs integrated with an on-chip 2 ppm/°C typical (5 ppm/°C maximum), 2.5 V reference. The on-chip reference can drive the reference input of all four AD5750-2s, has a low output impedance of 0.05 Ω, and can source and sink up to 5 mA.
The ADuM1301 is a triple-channel digital isolator. The ADuM5400 is a quad-channel digital isolator with an integrated, isolated, dc-to-dc converter. They are both based on iCoupler® technology and are used to provide isolation between the signal chain and the system microcontroller, with an isolation rating of 2.5 kV rms. The ADuM5400 provides an isolated 5 V power supply for the 5 V circuits in the secondary side.
The EVAL-CN0229-SDPZ board connects to ADI’s System Demonstration Platform (SDP) and is powered by a triple output DC power supply of +15 V, -15 V and 6 V.
Do not connect the USB cable to the Mini-USB connector on the SDP board before turning on the dc power supply for the EVAL-CN0229-SDPZ.
See image below for jumper settings. The bolded values are the default settings for the EVAL-CN0229-SPDZ.
NOTE: It is recommended that you install the CN0229 Evaluation Software to the default directory path C:\Program Files (x86)\Analog Devices\CN0229\ and all National Instruments products to C:\Program Files\National Instruments\
NOTE: It is recommended that you close all other applications before clicking “Next”. This will make it possible to update relevant system files without having to reboot your computer.
