ADS42xx EVM
This is the user’s guide for the ADS42xx EVM Rev B (EVM). The ADS42xx (dual channel, 12-bit and 14-
bit, up to 250 MSPS) is a dual analog-to-digital converter family. This EVM is specifically suited for
interfacing with TI’s TSW1400 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.
