Product Overview

The AD7903BRQZ is a dual differential successive approximation Analog-to-digital Converter (ADC) that operates from a single power supply VDDx per ADC. It contains two low power, high speed 16-bit sampling ADC and a versatile serial port interface (SPI). On the CNVx rising edge, the converter samples the voltage difference between the INx+ and INx- pins. The voltages on these pins usually swing in opposite phases between 0V and VREF. The externally applied reference voltage of the REFx pins (VREF) can be set independently from the supply voltage pins VDDx. The power of the device scales linearly with throughput. Using the SDIx inputs, the SPI-compatible serial interface can also daisy-chain multiple ADCs on a single 3-wire bus and provide an optional busy indicator.
  • 16-bit resolution with no missing codes
  • Low power dissipation
  • True differential analog input range - ±VREF
  • Allows use of any input range
  • Easy to drive with the ADA4941-1
  • No pipeline delay
  • Single-supply 2.5V operation with 1.8/2.5/3/5V logic interface
  • Serial port interface - SPI®/QSPI™/MICROWIRE™/DSP compatible
