GENERAL DESCRIPTION
The AD7366/AD73671
The AD7366/AD7367 are fabricated on the Analog Devices, Inc.,
industrial CMOS process (iCMOS
are dual 12-bit/14-bit, high speed, low
power, successive approximation analog-to-digital converters
(ADCs) that feature throughput rates up to 1 MSPS. The device
contains two ADCs, each preceded by a 2-channel multiplexer,
and a low noise, wide bandwidth track-and-hold amplifier.
The AD7366/AD7367 have an on-chip 2.5 V reference that
can be disabled to allow the use of an external reference.
If a 3 V reference is applied to the DCAPA andDCAPB pins, the
AD7366/AD7367 can accept a true bipolar ±12 V analog input.
Minimum ±12 V VDD and VSS supplies are required for the
±12 V input range.
), which is a technology
platform combining the advantages of low and high voltage
CMOS. The iCMOS process allows the AD7366/AD7367 to
accept high voltage bipolar signals in addition to reducing
power consumption and package size. The AD7366/AD7367
can accept true bipolar analog input signals in the ±10 V range,
±5 V range, and 0 V to 10 V range.
PRODUCT HIGHLIGHTS
1. The AD7366/AD7367 can accept true bipolar analog input
signals, as well as ±10 V, ±5 V, ±12 V (with external refer-
ence), and 0 V to 10 V unipolar signals.
2. Two complete ADC functions allow simultaneous sampling
and conversion of two channels.
3. 1 MSPS serial interface: SPI-/QSPI-/DSP-/MICROWIRE-
compatible interface.

2 iCMOS Process Technology. For analog systems designers within
industrial/instrumentation equipment OEMs who need high performance
ICs at higher voltage levels, iCMOS is a technology platform that enables the
development of analog ICs capable of 30 V and operating at ±15 V supplies
while allowing dramatic reductions in power consumption and package size,
and increased ac and dc performance.
