OP27: O2perational amplifier OP27G

Part Number: OP27

When the operational amplifier OP27G is powered by dual power supplies, the positive power supply is connected to +6.7V, and the negative power supply is connected to -16.6V. Can the operational amplifier work normally?

  • Hi Rose,

    yes, this is possible. But keep in mind, that the OP27 is a very old legacy part and is no rail-to-rail OPAmp. The common mode input voltage would need to stay at least 4V away from the rails. Translated to your application this would mean that the common mode input voltage should be within -12.6V and +2.7V.

    See also figure 6 of datasheet which shows typicals. Look at (16.6V + 6.7V) / 2 = +/-11.65V and calculate accordingly Relaxed


  • Hi Rose,

    I think that Kai has answered your inquiry. The specification is captured via OP27A/C, OP27G version may be slightly different.
