ADS42B4x EVM
This is the user’s guide for the ADS42B4x EVM (Revision A). The ADS42B49 (dual-channel, 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, Bill of
Materials (BOM), and layout files are found in the design package in the ADS42B4x EVM product folder
on
