  • Dayton DTA-2 Quiescent Current

    Has anyone tested, or does anyone have the spec for, the Dayton DTA-2 amp's idle current, i.e., how much it draws when it is turned on but not receiving any input signal to amplify? This guy here:

    I am considering using this amp in a battery-powered application, but I would like to have that spec, and can't find it in the scant product literature. I'm aware that it is a Class D amp, but that in itself doesn't answer my question.

    Since no one here seemed to have the information I was seeking, I decided to answer my own question.

    With the DTA-2 hooked up to a 12 volt supply and turned on, but with no input or output signals, the idle current measured 61 mA.

    Perhaps that figure will be of use to some future builder.

      Thanks for posting back! A lot of folks wouldn't do that and you're right that someone may want to know.
