Circuit audio power amplifier btl tda7052


Circuit audio power amplifier with tda7052 BTL of 1 watt small size

The tda 7052 is an amplifier in package plastic dil of 8 pins. Drawn for equipments of portable radios supplies by batteries.

TDA7052 doesn’t request external components, it presents good stability, low consumption, without of heat-sink.

For not being necessary external components that integrated circuit he/she becomes ideal for applications where the space is minimum. The only components that were added to the circuit went a potentiometer to adjust the volume and bypass capacitors. That integrated circuit is a good substitute for the lm386. He requests from 6 to 12 volts for your feeding. It is very easy to set up an amplifier using the tda7052, you can add him/it to your projects where he/she needs an amplifier of potency of 1 watt.
