Features Dual Op Amp Circuitry (Typical for VS= 5V) Input offset voltage 0.6mV Input offset current 1nA Input bias current 3nA Common-mode input voltage range 0V to VS-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 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. Applications Low cost charging circuitry Power supplies and adapters

Reliability Metrics

Part Number	Process	EFR Reject	EFR Sample Size	PPM	LTA Rejects	LTA Device Hours	FITS	MTTF (Hours)
LM432MA	LB300	0	34371	0	0	4164500	1	1181688246
LM432MAX	LB300	0	34371	0	0	4164500	1	1181688246

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
