ADS42JB69 Analog-to-Digital Converter

The ADS42JB69 and ADS42JB49 are high-linearity, dual-channel, 16- and 14-bit, 250-MSPS, analog-todigital converters (ADCs). These devices support the JESD204B serial interface with data rates up to 3.125 Gbps. The buffered analog input provides uniform input impedance across a wide frequency range while minimizing sample-and-hold glitch energy making it easy.
