GENERAL DESCRIPTION

The MC13060 is a quasi–complementary audio power

amplifier, mounted in the SOP 8 (power SOIC package). It is

well suited to a variety of 1.0 W and 2.0 W applications in

radio, TV, intercom, and other speaker driving tasks. It

requires the usual external components for high frequency

stability and for gain adjustment.

The output signal voltage and the power supply drain

current are very linearly related, as shown in Figure 5. Both

are quite constant over wide variation of the power supply

voltage (above minimum VCC for clipping, of course). The

amplifier can best be described as a voltage source with

about 1.0 App capability. On a good heatsink, it can deliver

over 2.0 W at 70

°C ambient.

The MC13060 will automatically go into shutdown at a die

temperature of about 150

°C, effectively protecting itself, even

on fairly stiff power supplies. This eliminates the need for

decoupling the power supply, which degrades performance

and requires extra components.

Input Pins 5 and 8 are internally biased at 0.7 Vdc and

should not be driven below ground.
