LM432

Dual Op Amp with On-Chip Fixed 2.5V Reference

General Description

Features

The LM432 integrates two operational amplifiers and one

2.5V reference. The reference is based on the LMV431

adjustable shunt regulator with the output voltage adjusted

to a fixed 2.5V. The Op Amps are similar to the LM358 with

a common-mode input range that includes ground. Integrat-

ing the reference and Op Amps creates a solution for low

cost charging applications.
