## Description

Specifications: Amplifier Chip: TDA2050 Number of channels: one channel Input voltage: DC/AC 5-24V Output power: 5W-120W Output impedance: 4-16Ω Size: 60*35mm*40mm Note: 1. It's not suitable for mobile phone sound sources and truck power sources (the power can not exceed 24V 500MA and above), otherwise the sound quality is not good. 2. The positive and negative poles of the circuit must be connected correctly, otherwise the board may be damaged. 3. The power supply cannot be overloaded, otherwise it may damage or burn out the amplifier board. Package included: 2 x TDA2050 Mono Audio Amplifier Module

Review: Clean sound. - Worked as expected. I use a DC 12V power supply, connected an 8" full range speaker and tested with an electric guitar, sound is not very loud but clean. will be use as a practice amp.
Review: Good parts - used this in a RC car for sound effects

### ⭐⭐⭐⭐⭐ Clean sound.

Worked as expected. I use a DC 12V power supply, connected an 8" full range speaker and tested with an electric guitar, sound is not very loud but clean. will be use as a practice amp.

### ⭐⭐⭐⭐⭐ Good parts

### ⭐⭐⭐⭐ Heat Sink for high power
*by G***N on May 21, 2025*

The circuit is simply from the TDA2050 application notes so it is all good. However, the heat sink is probably undersized. For 20 watts audio out, the Heat sink should be about 3 degrees C/Watt. The heat sink on the board is about 10 degrees C/Watt. (add a watt the chip temp goes up +10C) The chip automatically shuts down when overheating, so if volume is high, it will clip, and more noticeable in the base. So as is, it should run fine up to about 7 to 10 watts which covers most single room and headphone to speaker applications. To get to 15 or 20 Watts or more, just add a bigger heat sink. Great value for the price!
