GENERAL DESCRIPTION
The AD7366-5/AD7367-51 are dual, 12-/14-bit, low power,
successive approximation analog-to-digital converters (ADCs)
that feature throughput rates up to 500 kSPS. Each device contains
two ADCs, which are both preceded by a 2-channel multiplexer,
and a low noise, wide bandwidth, track-and-hold amplifier.
The AD7366-5/AD7367-5 are fabricated on the Analog
Devices, Inc., industrial CMOS process (iCMOS)2, which is
a technology platform combining the advantages of low and
high voltage CMOS. The process allows the parts to accept
high voltage bipolar signals in addition to reducing power
consumption and package size. The AD7366-5/AD7367-5 can
accept true bipolar analog input signals in the ±10 V range,
±5 V range, and 0 V to +10 V range.
1 Protected by U.S. Patent No. 6,731,232.
2 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.
The devices 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 and DCAPB pins, the AD7366-5/AD7367-5 can
accept a true bipolar ±12 V analog input. Minimum ±12 V VDD
and VSS supplies are required for the ±12 V input range.
PRODUCT HIGHLIGHTS
1.
True bipolar analog input signals can be accepted, as well
as ±10 V, ±5 V, ±12 V (with external reference), and 0 V to
+10 V unipolar signals.
2.
Two complete ADC functions allow simultaneous
sampling and conversion of two channels.
3.
A 500 kSPS serial interface is SPI-/QSPI-/MICROWIRE-/
DSP-compatible.
