ADS42LBx9EVM
The ADS42LB49 and ADS42LB69 are dual-channel, 250-MSPS, analog-to-digital converters that are 14-
bit and 16-bit resolutions, respectively. The ADS42LB49EVM and ADS42LB69EVM (ADS42LBx9EVM) are
specifically suited for interfacing with TI’s TSW1400EVM to capture and display waveforms from the ADC.
The EVM schematic, BOM, and layout files are found in the design package in the ADS42LBx9EVM
product folder on www.ti.com.
