GENERAL DESCRIPTION

The AD7952 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 AD7952 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

samples the fully differential analog inputs on IN+ and IN−.

The AD7952 features four different analog input ranges and three

different sampling modes: warp mode for the fastest throughput,

normal mode for the fastest asynchronous throughput, and

impulse mode where power is scaled with throughput.

Operation is specified from −40°C to +85°C.
