This low power audio amplifier schematic circuit is based on the TDA8541 amplifier IC which is capable to deliver a maximum output power of 1.2 W into a 8 ohms load using a 5 volts power supply . The TDA8541 audio power amplifier can be used in small applications for low power devices  .
The TDA8541 power amplifier  contains  a Bridge Tied Load (BTL) amplifier with a complementary PNP-NPN output stage.

The build of circuit is very simple requiring few external components  making it ideal for audio stages of small devices .
Other features of this 1 W audio amplifier are : low saturation voltage of output stage , gain can be fixed with external resistors , standby mode controlled by CMOS compatible levels , low standby current , high supply voltage ripple rejection , outputs short-circuit safe to ground - VCC and across the load , thermally protected and other .
