    General Description

    The LMV641 is a low power, wide bandwidth operational amplifier with an extended power supply voltage range of 2.7V to 12V.

    It features 10 MHz of gain bandwidth product with unity gain stability on a typical supply current of 138 μA. Other key specifications are a PSRR of 105 dB, CMRR of 120 dB, VOS of 500 μV, input referred voltage noise of 14 nV/ , and a THD of 0.002%. This amplifier has a rail-to-rail output stage, and a common mode input voltage which includes the negative supply.

    The LMV641 operates over a temperature range of −40°C to +125°C and is offered in the board space saving 5-Pin SC70 and 8-Pin SOIC packages.

    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.
