GENERAL DESCRIPTION
The AD7903 is a dual 16-bit, 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 ADCs and a versatile
serial port interface (SPI). On the CNVx rising edge, the AD7903 samples the
voltage difference between the INx+ and INx− pins. The voltages on these pins
usually swing in opposite phases between 0 V 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. It is compatible with 1.8 V, 2.5 V, 3 V, or 5 V logic, using the
separate VIOx supplies.
The AD7903 is available in a 20-lead QSOP package with operation specified
from −40°C to +125°C.
