This is the user's guide for the ADS42xx EVM (Revision B). The ADS42xx is a dual channel 12-bit/14-bit,
up to 250MSPS dual analog-to-digital converter family. This EVM is specifically suited for interfacing with
TI's TSW1200 EVM to capture and display waveforms from the ADC. The EVM schematic, BOM, and
layout files can be found in the design package in the ADS42xx EVM product folder on www.ti.com.
