EVAL-AD7124-4ASDZ/EVAL-AD7124-8ASDZ Evaluation Board User Guide
User guide for EVAL-AD7124-4ASDZ/8ASDZ boards evaluating AD7124-4/8 24-bit sigma-delta ADCs with on-board ADR4525 reference and ADP150 regulators.
Overview
This document describes the hardware and software setup for the EVAL-AD7124-4ASDZ and EVAL-AD7124-8ASDZ evaluation kits. These kits feature the AD7124-4 and AD7124-8, which are 24-bit, low-noise, low-power sigma-delta ADCs. The evaluation boards include an on-board 2.5V ADR4525 reference and utilize ADP150 and ADP7182 regulators for power management. The guide provides detailed information on hardware link options, power supply configurations (including 3.3V and ±1.8V split supply), and serial interface connectivity via the EVAL-SDP-CB1Z controller, PMOD connectors, or Arduino-compatible headers. It also includes instructions for using the AD7124 Eval+ software for time-domain and noise analysis.
Use Cases
- Evaluating ADC noise and performance characteristics
- Prototyping precision sensor interfaces for RTDs and thermocouples
- Developing 4-wire bridge measurement systems
- Software-based data analysis and ADC register configuration
