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
