Two-channel Speaker amplifier TEA2025B
This small and compact two channel speaker amplifier has the ability to amplify stereo sound up to 3W on each channel. You can also adjust the volume on the amplifier to increase or decrease the output volume of the speakers. Even though the module can operate on 3V, you will not be able to get 3W output to the speakers with a power supply of 3V. In order to get 3W on each channel, you need to use a power supply of 12V - 15V.
Technical specifications:
Min input voltage | 3V |
Max input voltage | 15V |
Max output current | 1.5A |
