NE5532

Other Parts Discussed in Thread: NE5532

Customer are using the TI NE5532 OPAMP  in a single supply connectivity.

We supply +24V to GND.

The maximum voltage is +22V while the recommended operating voltage is +15V.

 Is that OK?

    Eli,

    As long as you don't exceed (Vcc+ - Vcc-) > 30V, you should be OK.  +24V on Vcc+ and Gnd on Vcc- should operate fine.  Keep in mind, since the voltage mid-point is now 12V, everything else will be biased to 12V accordingly.

    Jef,

    When you said that “the voltage mid-point is now 12V, everything else will be biased to 12V accordingly” you mean that the internally (in the chip) everything is biased to 12V.

    If so, I don’t care, since I need the output of the device, and it can get from 0v to VCC (24v) (minus the rails).

    Eli,

    That's correct.  I meant only that the input common mode is now around 2V to 22V and the output swing is going to be around 2V to 22V as well.  If you're looking to have the output swing to ground, you'll run into issues.
