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 the signal chain, reduces power consumption for precision applications, and supports high-frequency signals beyond 1MHz. By not requiring an external decoupling capacitor, the integrated ADC reference buffer is optimized for wide bandwidth applications.
The ADS922x uses a serial LVDS (SLVDS) data interface that enables high-speed digital interface while minimizing digital switching noise. Read the dual-channel ADC data using separate SLVDS outputs per ADC channel or one SLVDS output for both ADC channels.
