LMP2012QML-SP: LMP2012QML-SP max. supply voltage

Daniel Bieri
Prodigy 10 points

Part Number: LMP2012QML-SP

The datasheet of the LMP2012QML-SP OPAMP specifies the absloute maximum limit of the supply voltage to be 5.8V. Do i understand correctly that this referes to the voltage difference between the two supply pin i.e. V+ - V-? So using this part with V+=+5V, V-=0V or V+=+2.5V, V-=-2.5V is ok but V+=+5V, V-=-5V would exceed the specification.

    Hello Daniel,

    Yes. Correct.

    Op-amps do not have "ground" pins, so the amplifier lives "between" the supplies.

    VS = (V+) – (V–)

    V+= +5, V- = 0V (GND) = +5V total. OK.

    V+= +2.5, V- = -2.5V = +5V total. OK

    V+= +5, V- = -5V  = +10V total. NOT OK because > +5.8V.
