Features (Typical 5V supply, unless otherwise noted) Input referred voltage noise 5.8 nV/ Input bias current 100 fA Unity gain bandwidth 17 MHz Supply current per channel LMV796 1.15 mA LMV797 1.30 mA 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 LMV796 (Single) and the LMV797 (Dual) low noise, CMOS input operational amplifiers offer a low input voltage noise density of 5.8 nV/ while consuming only 1.15 mA (LMV796) of quiescent current. The LMV796 and LMV797 are unity gain stable op amps and have gain bandwidth of 17 MHz. The LMV796/ LMV797 have a supply voltage range of 1.8V to 5.5V and can operate from a single supply. The LMV796/LMV797 each feature a rail-to-rail output stage capable of driving a 600Ω load and sourcing as much as 60 mA of current. The LMV796 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 LMV796 and the LMV797 ideal for low power sensor applications. The LMV796/LMV797 are manufactured using National’s advanced VIP50 process and are offered in a 5-pin SOT23 and an 8-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.
