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.

Product Highlights

Programmable input range and mode selection. Pins or serial port for selecting input range/mode select.
Fast throughput. In warp mode, the AD7612 is 750 kSPS.
Superior Linearity. No missing 16-bit code. ±1.5 LSB max INL.
Internal Reference. 5 V internal reference with a typical drift of ±3 ppm/°C and an on-chip temperature sensor.
Serial or Parallel Interface. Versatile parallel (16- or 8-bit bus) or 2-wire serial interface arrangement compatible with 3.3 V or 5 V logic.
