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.
