 ====== EVAL-CN0552-PMDZ Overview ======
-The ** EVAL-CN0552-PMDZ ** is a [[https://reference.digilentinc.com/pmod/start|PMOD]] form-factor evaluation board for the [[ADI>AD7746]], a high resolution, Σ-Δ capacitance-to-digital converter (CDC). The architecture features inherent high resolution (24-bit no missing codes, up to 21-bit effective resolution), high linearity (±0.01%), and high accuracy (±4 fF factory calibrated).

-The AD7746 capacitance input range is ±4pF (changing), while it can accept up to 17pF common-mode capacitance (not changing), which can be balanced by a programmable on-ship, digital-to-capacitance converter (CAPDAC). The AD7746 has two capacitive inputs. Each channel can be configured as single-ended or differential.
+The [[ADI>CN0552|CN0552]] has two capacitive inputs with each channel that can be configured as single-ended or differential. The capacitance input range is ±4.096 pF at a maximum bulk capacitance of 17 pF but is capable of extending up to ±50 pF with a maximum bulk capacitance of 200 pF which can be balanced by a programmable on-chip, digital-to-capacitance converter (CAPDAC).

-The AD7746 communicates via a 2-wire, I2C-compatible serial interface. It can operate with a single power supply from 2.7V to 5.25V.
+The output data rate is adjustable from 9.1 sps to 90.9 sps, with the 16.1 sps setting providing strong rejection of both 50Hz and 60Hz power line noise. The CDC also provides temperature measurement with a resolution of 0.1°C and accuracy of ±2° C for temperature compensation and system calibration.
+The CN0552 is compatible with I2C PMOD platform boards, with an I/O voltage from 2.7 V to 5.5 V.

-  * The ADICUP3029 example application uses the AD7746 no-OS driver and emulates the Linux IIO framework through the tinyiiod daemon library. The application communicates with the host computer via the serial backend, over a USB-UART physical connection. This facilitates rapid application development on a host computer, independent from embedded code development.

The application communicates with the host computer via the serial backend, over a USB-UART physical connection. This facilitates rapid application development on a host computer, independent from embedded code development.
 . **Raspberry Pi**\\
-  * The Linux driver uses the Industrial Input/Output (IIO) framework, greatly simplifying the development of application code via the cross-platform Libiio library, which is written in C and includes bindings for Python, MATLAB, C#, and other languages. Application code can run directly on the platform board, communicating with the device over the local backend, or from a remote host over the network or USB backends.\\
