    Description:

    National Semiconductor offers this blank universal Evaluation Board to help you evaluate the performance of any low voltage, low power operational amplifier that is offered in the SC-70 package. Resistors, capacitors, or any other components can be easily mounted on this board. These components can be chosen from any of the following three popular sizes: 1206, 0805, and, 0603. The op amp can then be tested under the conditions of your choice.

    The 551012922-001 Evaluation Board allows quick and easy evaluation of the part. You need only supply an analog input signaland a power supply to the evaluation board.

    Features:

    • Universal for all low voltage, low power op amps.
    • Dual sided layout for different pin-outs.
    • Accommodates components of any of these sizes:
           1206
           0805
           0603
    • Quick and easy evaluation.

    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.
