GENERAL DESCRIPTION
The AD7612 is a 16-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 AD7612 contains a high speed
16-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 AD7612 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 consumption is
scaled linearly with throughput. Operation is specified from
40°C to +85°C.
