hi,

       what is the recommended operation Vcc range? From Figure.5 in datasheet, does it mean that the VCC range  +-5Vmin----+-18Vmax?

    Hi Ken,

    this figure only shows the tyical performance of LF353. This figure does not guarantee that the OPAmp works down to +/-5V and below.

    On page 11 the datasheet says:

    "Each amplifier is individually biased by a zener reference which allows normal circuit operation on ±6V power supplies. Supply voltages less than these may result in lower gain bandwidth and slew rate."

    And footnote (3) on page 4 says:

    "Supply voltage rejection ratio is measured for both supply magnitudes increasing or decreasing simultaneously in accordance with
    common practice. VS = ±6V to ±15V."

    So, I would say the recommended supply voltage range is +/-6V to +/-15V.
