TLV2553EVM-PDK Evaluation Module

SBAU247A – June 2015 – Revised September 2019

TLV2553EVM-PDK Evaluation Module

This user's guide describes the characteristics, operation, and use of the TLV2553EVM performance
demonstration kit (PDK). This kit is an evaluation platform for the

TLV2553

which is a 12-bit, 200-kSPS,

successive approximation register (SAR), analog-to-digital converter (ADC) that features an 11-channel
analog input multiplexer and a serial SPI™ digital output interface. The EVM eases the evaluation of the
TLV2553 device with hardware and software for computer connectivity through the universal serial bus
(USB) interface. This user's guide includes complete circuit descriptions, schematic diagrams, and a bill of
materials.

The following related documents are available through the Texas Instruments web site at
