General Description

National’s LMV861 and LMV862 are CMOS input, low power op amp IC's, providing a low input bias current, a wide temperature range of −40°C to +125°C and exceptional performance making them robust general purpose parts. Additionally, the LMV861 and LMV862 are EMI hardened to minimize any interference so they are ideal for EMI sensitive applications.

The unity gain stable LMV861 and LMV862 feature 30 MHz of bandwidth while consuming only 2.25 mA of current per channel. These parts also maintain stability for capacitive loads as large as 200 pF. The LMV861 and LMV862 provide superior performance and economy in terms of power and space usage.

This family of parts has a maximum input offset voltage of 1 mV, a rail-to-rail output stage and an input common-mode voltage range that includes ground. Over an operating range from 2.7V to 5.5V the LMV861 and LMV862 provide a PSRR of 93 dB, and a CMRR of 93 dB. The LMV861 is offered in the space saving 5-Pin SC70 package, and the LMV862 in the 8-Pin MSOP.

Reliability Metrics

Part Number	Process	EFR Sample Size	LTA Device Hours	FITS	MTTF (Hours)
LMV861MG	CMOS7	18406	1089000	4	309006723
LMV861MGE	CMOS7	18406	1089000	4	309006723
LMV861MGX	CMOS7	18406	1089000	4	309006723

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.
