ADS5294, 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 ADS5294 analog-to-digital converters (ADC), which collectively are 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.
