The ADS922x is a family of 16-bit, high-speed, dual-channel, simultaneous-sampling, analog-to-digital converter (ADC) with an integrated driver for the ADC inputs. The integrated ADC driver simplifies external signal-chain that can be optimized for low-power and high-precision. The ADC consumes only 141 mW/ch at 10 MSPS/ch and the power consumption scales with lower sampling rates.
The ADS922x uses a serial LVDS (SLVDS) data interface that enables high-speed digital interface while minimizing digital switching noise. The dual-channel ADC data can be read using separate SLVDS outputs per ADC channel or one SLVDS output for both ADC channels.
