Features (VCC = 5V, TA = 25°C. Typical values unless specified). Gain-Bandwidth product 1MHz Low supply current 430µA Low input bias current 45nA Wide supply voltage range +3V to +32V Stable with high capacitive loads   Single version of LM324   Description The LM321 brings performance and economy to low power systems. With a high unity gain frequency and a guaranteed 0.4V/µs slew rate, the quiescent current is only 430µA/amplifier (5V). The input common mode range includes ground and therefore the device is able to operate in single supply applications as well as in dual supply applications. It is also capable of comfortably driving large capacitive loads. The LM321 is available in the SOT23-5 package. Overall the LM321 is a low power, wide supply range performance op amp that can be designed into a wide range of applications at an economical price without sacrificing valuable board space. Applications Chargers Power supplies Industrial: controls, instruments Desktops Communications infrastructure

Reliability Metrics

Part Number	Process	EFR Reject	EFR Sample Size	PPM	LTA Rejects	LTA Device Hours	FITS	MTTF (Hours)
LM321MF	LB300	0	34371	0	0	4164500	1	1181688246
LM321MFX	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.
