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

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.
