LM432 Datasheet | National Semiconductor

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 mon-mode input range that includes ground. Integrating the reference and Op Amps creates a solution for low cost charging applications.
