CAP DAC IN– The AD7951 is a 14-bit, charge redistribution, successive
approximation register (SAR) architecture analog-to-digital
converter (ADC) fabricated on Analog Devices, Inc.’s iCMOS
high voltage process. The device is configured through hardware or
via a dedicated write only serial configuration port for input
range and operating mode. The AD7951 contains a high speed
14-bit sampling ADC, an internal conversion clock, an internal
reference (and buffer), error correction circuits, and both serial
and parallel system interface ports. A falling edge on CNVST
samples the analog input on IN+ with respect to a ground
sense, IN−. The AD7951 features four different analog input …
