Dual-Channel, 16-Bit, 250-MSPS Analog-to-Digital Converter (ADC) - ADS42JB69

ADS42JB69 (ACTIVE)

Dual-Channel, 16-Bit, 250-MSPS Analog-to-Digital Converter (ADC)

 

Description

The ADS42JB69 and ADS42JB49 are high-linearity, dual-channel, 16- and 14-bit, 250-MSPS, analog-to-digital 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 to drive analog inputs up to very high input frequencies. A sampling clock divider allows more flexibility for system clock architecture design. The devices employ internal dither algorithms to provide excellent spurious-free dynamic range (SFDR) over a large input frequency range.

For all available packages, see the orderable addendum at the end of the datasheet.
