Features (Typical 5V supply, unless otherwise noted) Input referred voltage noise 5.8 nV/ √Hz Input bias current 100 fA Unity gain bandwidth 17 MHz Supply current per channel enable mode LMV791 1.15 mA LMV792 1.30 mA Supply current per channel in shutdown mode 0.02 µA Rail-to-rail output swing @ 10 kΩ load 25 mV from rail @ 2 kΩ load 45 mV from rail Guaranteed 2.5V and 5.0V performance Total harmonic distortion 0.01% @1 kHz, 600Ω Temperature range −40°C to 125°C Description The LMV791 (Single) and the LMV792 (Dual) low noise, CMOS input operational amplifiers offer a low input voltage noise density of 5.8 nV/ while consuming only 1.15 mA (LMV791) of quiescent current. The LMV791 and LMV792 are unity gain stable op amps and have gain bandwidth of 17 MHz. The LMV791/ LMV792 have a supply voltage range of 1.8V to 5.5V and can operate from a single supply. The LMV791/LMV792 each feature a rail-to-rail output stage capable of driving a 600Ω load and sourcing as much as 60 mA of current. The LMV791 family provides optimal performance in low voltage and low noise systems. A CMOS input stage, with typical input bias currents in the range of a few femtoAmperes, and an input common mode voltage range which includes ground make the LMV791 and the LMV792 ideal for low power sensor applications. The LMV791 family has a built-in enable feature which can be used to optimize power dissipation in low power applications. The LMV791/LMV792 are manufactured using National’s advanced VIP50 process and are offered in a 6-pin TSOT23 and a 10-pin MSOP package respectively. Applications • Photodiode amplifiers • Active filters and buffers • Low noise signal processing • Medical Instrumentation • Sensor interface applications

LMV791MKX	VIP50CLZ3	0	1755	0	0	315000	12	89382110

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.
