One Watt Audio Amplifier

This audio amplifier kit/circuit is normally used a building block for integration with other kits or your own circuits where there is a need for a mono audio amplifier. The audio amplifier IC is a TDA7052 from Phillips electronics.

The amplifier circuit is very small, yet it is capable of producing an audio output signal at about 1 Watt, needing a battery or DC voltage input of 3-15 Volts (VDC). 6 Volts is the optimum DC voltage level and the output impedance of the circuit is 8 Ohms.

The amplifier circuit has only a very small number of components and there is no need for a heatsink. Frequency response is in the audio range of 20 HZ to 20 kHz. Unit comes with datasheet.

Specifications:

• L: 1-3/16" W: 1-3/16" H: 5/8"
• Requires external 3-15 volt dc
• Output up to 1 watt
