Description
- Product Details
- The AD7612 is a 16-bit charge redistribution successive approximation register (SAR), architecture analog-to-digital converter (ADC) fabricated on Analog Devices, Inc."s _i_CMOS 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**
- 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.
- 4. Internal Reference. 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.
- **Applications**
- Process control
- Medical instruments
- High speed data acquisition
- Digital signal processing
