A 1-watt mono amplifier using the TDA7052

1W Mono Amplifier with IC TDA7052

This circuit is a 1-watt mono amplifier using the Philips TDA7052. It is designed as a building block in other projects where battery-powered audio amplifiers are needed to drive small speakers. It operates optimally at 6–12 V DC and requires no heatsink during normal use.

Circuit description:

There are only 5 external components. C1 is the input coupling capacitor, used to block any DC component that may be present in the input. C2 and C3 provide power supply decoupling, and R2 provides an adjustable input level. This can be used as a volume control.

element:

C1: 2.2 microfarad electrolytic capacitor

C2: 100 nanofarad ceramic capacitor

C3: 100µF electrolytic capacitor

R1: 1 kΩ resistor

R2: 10 kΩ logarithmic potentiometer
