1 / 9 page LM432 www.ti.com SNOS538D – AUGUST 2000 – REVISED MARCH 2013 LM432 Dual Op Amp with On-Chip Fixed 2.5V Reference Check for Samples: LM432 1 FEATURES APPLICATIONS 2 • Dual Op Amp Circuitry • Low Cost Charging Circuitry • (Typical for VS= 5V) • Power Supplies and Adapters • Input Offset Voltage 0.6mV DESCRIPTION • Input Offset Current 1nA The LM432 integrates two operational amplifiers and • Input Bias Current 3nA one 2.5V reference. The reference is based on the • Common-Mode Input Voltage Range 0V to LMV431 adjustable shunt regulator with the output VS−1V voltage adjusted to a fixed 2.5V. The Op Amps are similar to the LM358 with a common-mode input • Power Supply Current 150µA range that includes ground. Integrating the reference • Reference Circuitry and Op Amps creates a solution for low cost charging • Reference Voltage 2.5V applications. • Reference Voltage Deviation ( −40°C to 85°C) 4mV • Sink Current Capability 0.2mA to 10mA Connection Diagram Figure 1. 8-Pin SOIC (Top View) See Package Number D Application Circuit Figure 2.
