EVAL-AD7760EDZ/EVAL-AD7762EDZ Evaluation Board User Guide
User guide for the EVAL-AD7760EDZ and EVAL-AD7762EDZ evaluation boards, used to evaluate the AD7760 and AD7762 24-bit Sigma-Delta ADCs with the EVAL-CED1Z controller.
Overview
This user guide provides instructions for the EVAL-AD7760EDZ and EVAL-AD7762EDZ evaluation boards, designed to test the AD7760 and AD7762 24-bit Sigma-Delta analog-to-digital converters (ADCs). The AD7760 features high-speed performance with 100 dB SNR at 2.5 MSPS, while the AD7762 supports a maximum output data rate of 625 kSPS. The boards interface with the EVAL-CED1Z controller board via a USB link for data acquisition and analysis through dedicated software. The guide details hardware features including the on-board 4.096 V reference, crystal clock oscillator, and ADP3334 voltage regulators. It also covers software installation, link options, power supply requirements, and differential input routing through XLR connectors. Full schematics, PCB layout artwork, and a bill of materials are provided for design reference.
Use Cases
- Evaluating 24-bit Sigma-Delta ADC performance
- Developing high-speed data acquisition systems
- Testing custom programmable filters for ADCs
- Prototyping sensor interfaces with differential amplifiers
