ADS794xEVM-PDK
This user's guide describes the characteristics, operation, and use of the ADS794xEVM by itself and as
part of the ADS794xEVM-PDK kit. These evaluation modules (EVMs) allow evaluation of all aspects of
either the
ADS7946 or ADS7945 devices (ADS794x). Both devices are 14-bit, dual-channel, ultralow-
power, differential successive-approximation-register (SAR) analog-to-digital converters (ADCs) with a
maximum throughput rate of 2 MSPS. The ADS7945 offers fully-differential input voltages while the
pseudo-differential inputs of the ADS7946 offer single-ended input voltages with small common-mode
noise-cancelling capabilities. Complete circuit descriptions, schematic diagrams, and bill of materials are
included in this document.
