LC7972VA, 7972VB
CMOS Operational Amplifier with Programmable
Offset Correction Function
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.
• The following modes are supported. These are selected
via port level settings.
Package Dimensions
unit: mm
3179A-SSOP20
[LC7972VA, VB]
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
