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.
