LM432 Datasheet - National Semiconductor

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

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. Integrating the referenc.
