AD7192 Evaluation Board User Guide

The EVAL-AD7192ASDZ evaluation kit features the AD7192 which is 4.8 kHz ultralow noise 24-bit sigma-delta (Σ-Δ) ADCs.The on-chip low noise gain stage means that signals of small amplitude can interface directly to the ADC.The internal clock option provides a compact solution for low BW requirements.

The AD7192 ACE Plugin fully configures the AD7192 device register functionality and provides dc time domain analysis in the form of waveform graphs, histograms, and associated noise analysis for ADC performance evaluation.

Full specifications on the AD7192 are available in the product data sheet, which should be consulted in conjunction with this user guide when working with the evaluation board.

Required Software

Quick Start Guide

The following steps highlight the process to begin using the evaluation board.

Equipment Required

EVAL-AD7192ASDZ evaluation board
PC running Windows with a USB2.0 port and software installed.
Controller Board
1. Option A: EVAL-SDP-CK1Z and a USB-C cable
2. Option B: EVAL-SDP-CB1Z and a Micro-USB cable

Getting started

Ensure the SDP board is not connected to the USB port of the PC

Install the ACE Software

Ace Plugin Install guide available here

If ACE Software is already installed, update the Plugins to download AD719x Plugin.

Connect the EVAL-AD7192ASDZ to the controller board
Option A: Connect the EVAL-AD7192ASDZ to the EVAL-SDP-CK1Z
1. Using the 120 pin connector
  - Screw the two boards together using the plastic screw-washer set included in the evaluation board kit to ensure that the boards are connected firmly together.
2. Using the Arduino Connectors
Option B: Connect the EVAL-AD7192ASDZ to the EVAL-SDP-CB1Z
- Using the 120 pin connector
  - Screw the two boards together using the plastic screw-washer set included in the evaluation board kit to ensure that the boards are connected firmly together.
If using Windows® XP, it may be needed to search for the controller board drivers. Choose to automatically search for the drivers for the controller board if prompted by the operating system.
Launch the ACE plugin from the Analog Devices subfolder in the Programs Menu.
The Low Noise Test Demo is a useful demo mode of the Ace Plugin software to ensure that the Evaluation board is communicating correctly with the Ace Plugin software.
