Description

The ADS42JB46 is a high-linearity, dual-channel, 14-bit, 160-MSPS, analog-to-digital converter (ADC). This device supports 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, thus making driving analog inputs up to very high input frequencies easy. A sampling clock divider allows more flexibility for system clock architecture design. The device employs internal dither algorithms to provide excellent spurious-free dynamic range (SFDR) over a large input frequency range.
