ADS5295, 8-Channel, Analog-to-Digital Converter
This user's guide gives a general overview of the evaluation module (EVM) and provides a general
description of the features and functions to be considered while using this module. This manual is
applicable to the ADS5295 analog-to-digital converters (ADC), which, with the ADS5292 and ADS5294,
are collectively referred to as ADS529x. Use this document in combination with the respective ADC data
sheet. The ADS529xEVM provides a platform for evaluating the ADC under various signal, clock,
reference, and power supply conditions.
