GENERAL DESCRIPTION
The AD7366/AD7367
1
are dual, 12/14-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 are fabricated on the Analog Devices,
Inc. industrial CMOS process (
i
CMOS
2
), which is a technology
platform combining the advantages of low and high voltage
CMOS. The process allows the AD7366/AD7367 to accept high
voltage bipolar signals in addition to reducing power consump-
tion 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.
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 D
CAP
A and
D
CAP
B pins, the
AD7366/AD7367 can accept a true bipolar ±12 V analog input.
Minimum ±12 V V
DD
and V
SS
supplies are required for the
±12 V input 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.
