LM432
Dual Op Amp with On-Chip Fixed 2.5V Reference
General Description

The LM432 integrates two operational amplifiers and one
2.5V reference. The referenceis basedon the LMV431
adjustable shunt regulator with the output voltage adjusteda fixed 2.5V. TheOp Amps are similarto the LM358 with common-mode input range that includes ground. Integrat-
ing the reference andOp Amps createsa solutionfor low
cost charging applications.
Applications
Low cost charging circuitry Power supplies and adapters
