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 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.
