GENERAL DESCRIPTION

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.

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.
