KAmodLM4950

Description

KAmodLM4950 - 2x3 W power amplifier.

Audio power amplifier module based on the LM4950 circuit. It has two 3 W channels. The amplifier is powered by a voltage ranging from 10 to 15 V connected to a screw connector. The audio input is led out on a standard 3.5 mm Jack connector, while the speaker outputs are available on screw connectors. The module provides good sound quality with low power consumption, is compact and easy to use. It is ideal for low-power audio systems such as portable music players, computer speakers, portable radios, etc. It can also be used in service as an alternative to the original, damaged amplifier.
