AD7612BCPZ-RL
16位750 kSPS时,单极/双极性可编程输入的PulSAR ADC 16-Bit, 750 kSPS, Unipolar/Bipolar Programmable Input PulSAR ADC
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.
