GENERAL DESCRIPTION
The AD73671 is a dual, 14-bit, high speed, low power, successive
approximation ADC that features 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 that can handle input frequencies in excess
of 10 MHz.
The AD7367 is fabricated on Analog Devices’ Industrial CMOS
process, iCMOS, a technology platform combining the
advantages of low and high voltage CMOS, bipolar and high
voltage DMOS processes. The process allows the AD7367 to
accept high voltage bipolar signals in addition to reducing
power consumption and package size.
The AD7367 can accept true bipolar analog input signals in the
±10 V range, ±5 V range and 0 to 10 V range.
The AD7367 has an on-chip 2.5 V reference that can be
overdriven if an external reference is preferred. The AD7367 is
available in a 24-lead TSSOP package.
1Protected by U.S. Patent No. 6,681,332.

iCMOSTM 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 30V and operating at +/- 15V supplies while allowing dramatic reductions in power consumption and
package size, and increased AC and DC performance.
