3 Description
The ADS922x is a family of 16-bit, high-speed, dualchannel,
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 dualchannel
ADC data can be read using separate SLVDS
outputs per ADC channel or one SLVDS output for
both ADC channels.
