Overview

The LC7972VA and LC7972VB are dual inverting/noninverting operational amplifier ICs that are fabricated in a CMOS process. These ICs provide a programmable offset correction function and a power saving function for use when the operational amplifier is unused, both of which can be controlled from a microprocessor interface.

Features

• High input impedance provided by fabrication in a

CMOS process.

• Low power provided by fabrication in a CMOS process.

• One of two types of operational amplifier can be

selected: inverting (operational amplifier 1) or

noninverting (operational amplifier 2)

• Operating supply voltage: 4.9 to 5.2 V

• Package: SSOP20

• Operating temperature: Ta = –30 to +70°C

• The following modes are supported. These are selected

via port level settings.
