1W Mono Amplifier with IC TDA7052

This circuit is a 1 watt mono amplifier using the TDA 7052 from Philips. It is designed

to be used as a building block in other projects where a battery powered audio

amplifier is required to drive a small speaker. It will operate best from 6 – 12 V DC and

requires no heatsink for normal use.

Amplifier with IC TDA7052

Circuit Description :

There are only 5 external components. C1 is the input coupling capacitor, which blocks any DC that might be present on the input. C2 and C3 provide power supply decoupling, and R2 provides adjustable input level. This can be used as a volume control.

Components :

C1 : 2.2uF electrolytic capacitor

C2 : 100nF ceramic/mono

C3 : 100uF electrolytic

R1 : 1K ohm resistor

R2 : 10K ohm log potentiometer

Spindle for potentiometer
