GENERAL DESCRIPTION
The AD73281 is an 8-channel, 12-bit plus sign successive
approximation ADC designed on the iCMOS (industrial
CMOS) process. iCMOS is a process combining high voltage
silicon with submicron CMOS and complementary bipolar
technologies. It enables the development of a wide range of high
performance analog ICs capable of 33 V operation in a footprint
that no previous generation of high voltage parts could achieve.
Unlike analog ICs using conventional CMOS processes, iCMOS
components can accept bipolar input signals while providing
increased performance, dramatically reduced power consumption,
and reduced package size.
The AD7328 can accept true bipolar analog input signals. The
AD7328 has four software-selectable input ranges: ±10 V, ±5 V,
±2.5 V, and 0 V to +10 V. Each analog input channel can be
independently programmed to one of the four input ranges. The
analog input channels on the AD7328 can be programmed to be
single-ended, true differential, or pseudo differential.
The ADC contains a 2.5 V internal reference. The AD7328 also
allows for external reference operation. If a 3 V reference is applied
to the REFIN/OUT pin, the AD7328 can accept a true bipolar
±12 V analog input. Minimum ±12 V VDD and VSS supplies are
required for the ±12 V input range. The ADC has a high speed
serial interface that can operate at throughput rates up to 1 MSPS.

±10 V, ±5 V, ±2.5 V, and 0 V to +10 V unipolar signals.
2. The eight analog inputs can be configured as eight single-
ended inputs, four true differential input pairs, four pseudo
differential inputs, or seven pseudo differential inputs.
3. 1 MSPS serial interface. SPI-/QSPI-/DSP-/MICROWIRE-
compatible interface.
4. Low power, 31 mW, at a maximum throughput rate of
1 MSPS.
5. Channel sequencer.
