LC7972VA, 7972VB

CMOS Operational Amplifier with Programmable

Offset Correction Function

• The following modes are supported. These are selected

via port level settings.

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.

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

SANYO: SSOP20

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

Port

Level

Function

Operational amplifier 1: Operation stopped (low-power mode)

OP1ON

Operational amplifier 1: Normal operation (OP2ON must be low in this mode.)

Operational amplifier 2: Operation stopped (low-power mode)

OP2ON

OFST1

Operational amplifier 2: Normal operation (OP1ON must be low in this mode.)

Operational amplifier 1: Offset mode (inverting input = V_SS

Operational amplifier 1: Operating mode (inverting input = normal input)

Operational amplifier 2: Offset mode (noninverting input = V_SS

)

OFST2

CLKC

Operational amplifier 2: Operating mode (noninverting input = normal input)

Operational amplifier power supply clock: Internal clock
