AD7631BSTZ Product Details

The AD7631BSTZ is a 18-bit differential programmable input PulSAR® Analog-to-digital Converter (ADC) with charge redistribution and successive approximation register architecture. It is fabricated on Analog Devices Inc, 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 converter contains an internal conversion clock, an internal reference, error correction circuits and both serial and parallel system interface ports. A falling edge on CNVST samples the fully differential analog inputs on IN+ and IN-. The converter features four different analog input ranges.

Feature

  • Multiple pins/software-programmable input ranges
  • Pins or serial SPI-compatible input ranges/mode selection
  • 18-bit resolution with no missing codes
  • iCMOS™ process technology
  • No pipeline delay
  • Parallel and serial 5/3.3V interface SPI/QSPI™/MICROWIRE™/DSP compatible

Applications

  • Process controls
  • High speed data acquisition
