LM432 - Dual Op-Amp

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.
