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

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.
