Power Supplies and Adapters 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. Integrating the reference
and Op Amps creates a solution for low cost charging …
