GENERAL DESCRIPTION
approximation analog-to-digital converter (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 conven-
tional CMOS processes, iCMOS components can accept bipolar
input signals while providing increased performance, dramati-
cally reduced power consumption, and reduced package size.
The AD7323 can accept true bipolar analog input signals. The
AD7323 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 AD7323 can be programmed
to be single-ended, true differential, or pseudo differential.
The ADC contains a 2.5 V internal reference. The AD7323 also
allows for external reference operation. If a 3 V reference is
applied to the REFIN/OUT pin, the AD7323 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 500 kSPS.
PRODUCT HIGHLIGHTS
1. The AD7323 can accept true bipolar analog input signals,
±10 V, ±5 V, and ±2.5 V, and 0 V to +10 V unipolar signals.
2. The four analog inputs can be configured as four single-
ended inputs, two true differential input pairs, two pseudo
differential inputs, or three pseudo differential inputs.
3. 500 kSPS serial interface. SPI-/QSPI-/DSP-/MICROWIRE-
compatible interface.
4. Low power, 18 mW, at a maximum throughput rate of
500 kSPS.
5. Channel sequencer.
