ADS7042EVM-PDK, ADS7049-Q1EVM-PDK, and
ADS7057EVM-PDK Evaluation Module
ABSTRACT
This user's guide describes the characteristics, operation, and use of the ADS7042EVM-PDK, ADS7049-
Q1EVM-PDK, and ADS7057EVM-PDK evaluation modules (EVM), referred to collectively as the
ADS704X-5XEVM-PDK
. Each kit functions as an evaluation platform for two different low-power, small-size,
general-purpose successive approximation register (SAR) analog-to-digital converters (ADCs). These ADCs
include the 12-bit, 1-MSPS, single-ended input ADS7042, the 12-bit, 2-MSPS, single-ended ADS7049-Q1, the
12-bit, 3-MSPS, differential input ADS7047, and the 14-bit, 2.5-MSPS, differential input ADS7057. Moreover,
unique EVM design enables evaluation of the entire family of ADS704x and ADS705x devices through
minor modifications. Finally, this EVM platform eases device analysis using hardware, software, and computer
connectivity through the universal serial bus (USB) interface.
This user's guide includes complete circuit descriptions, schematic diagrams, and a bill of materials. Throughout
this document, the abbreviation
EVM
and the term
evaluation module
are synonymous with any EVM
(ADS7042EVM-PDK, ADS7049-Q1EVM-PDK, or ADS7057EVM-PDK), unless otherwise noted.
