Power Dissipation

the process by which an electronic or electrical device produces heat (energy loss or waste) as an undesirable derivative of its primary action.

417mW

Output Current

The rated output current is the maximum load current that a power supply can provide at a specified ambient temperature. A power supply can never provide more current that it's rated output current unless there is a fault, such as short circuit at the load.

4.5V~35V

Quiescent Current

The quiescent current is defined as the current level in the amplifier when it is producing an output of zero.

250μA

Max Output Voltage

The maximum output voltage refers to the dynamic area beyond which the output is saturated in the positive or negative direction, and is limited according to the load resistance value.
