Features Unless otherwise noted, typical values at TA= 25°C, V + = 3.3V Supply voltage 2.7V to 5.5V Supply current (per channel) 240 µA Input offset voltage 1 mV max Input bias current 0.1 pA GBW 3.3 MHz EMIRR at 1.8 GHz 120 dB Input noise voltage at 1 kHz 12 nV/ √Hz Slew rate 2 V/µs Output voltage swing Rail-to-Rail Output current drive 30 mA Operating ambient temperature range −40°C to 125°C Description National’s LMV831, LMV832, and LMV834 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 LMV831/LMV832/LMV834 are EMI hardened to minimize any interference so they are ideal for EMI sensitive applications. The unity gain stable LMV831/LMV832/LMV834 feature 3.3 MHz of bandwidth while consuming only 0.24 mA of current per channel. These parts also maintain stability for capacitive loads as large as 200 pF. The LMV831/LMV832/LMV834 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 LMV831/LMV832/LMV834 provide a PSRR of 93 dB, and a CMRR of 91 dB. The LMV831 is offered in the space saving 5-Pin SC70 package, the LMV832 in the 8-Pin MSOP and the LMV834 is offered in the 14-Pin TSSOP package. Applications • Photodiode preamp • Piezoelectric sensors • Portable/battery-powered electronic equipment • Filters/buffers • PDAs/phone accessories

Reliability Metrics

Part Number	Process	EFR Reject	EFR Sample Size	PPM	LTA Rejects	LTA Device Hours	FITS	MTTF (Hours)
LMV834MT	CMOS7	0	18406	0	0	1089000	4	309006723
LMV834MTX	CMOS7	0	18406	0	0	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.
