Two-channel, simultaneous-sampling, 18-bit 10-MSPS SAR ADC with fully-differential ADC input driver

The ADS921x is a family of 18-bit, high-speed, dual-channel,

simultaneous-sampling, analog-to-digital converters (ADCs) 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 ADS921x uses a serial LVDS (SLVDS) data interface that enables high-speed

digital communication 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.
