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
amplifier can best be described as a voltage source with
about 1.0 A capability. On a good heatsink, it can deliver
pp
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.
