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  
PRODUCT HIGHLIGHTS  
1. Programmable input range and mode selection.  
Pins or serial port for selecting input range/mode select.  
2. Fast throughput.  
In warp mode, the AD7612 is 750 kSPS.  
3. Superior Linearity.  
No missing 16-bit code. 1.5 LSB max INL.  
CNVST  
and parallel system interface ports. A falling edge on  
4. Internal Reference.  
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.  
5 V internal reference with a typical drift of 3 ppm/°C  
and an on-chip temperature sensor.  
5. 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.
