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

Check for Samples: LM432

FEATURES

APPLICATIONS

•

Dual Op Amp Circuitry

(Typical for V_S= 5V)

•

Low Cost Charging Circuitry

Power Supplies and Adapters

Input Offset Voltage 0.6mV

Input Offset Current 1nA

Input Bias Current 3nA

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

applications.

Common-Mode Input Voltage Range 0V to

V_S−1V

•

Power Supply Current 150µA

Reference Circuitry

Reference Voltage 2.5V

Reference Voltage Deviation (−40°C to 85°C)

4mV

•

Sink Current Capability 0.2mA to 10mA
