• Dual Op Amp Circuitry
• Low Cost Charging Circuitry
• (Typical for V
S
= 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
V
S
−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
