Wiring Material

Using the LM1877 monolithic dual power amplifier can be designed a very simple audio amplifier circuit for small audio applications like portable devices .

This audio amplifier circuit is designed to deliver 2W per channel continuous into 8Ω loads. The LM1877 is designed to operate with a low number of external components, and still provide flexibility for use in stereo phonographs, tape recorders and AM-FM stereo receivers, etc.
Each power amplifier is biased from a common internal regulator to provide high power supply rejection, and output Q point centering. The LM1877 is internally compensated for all gains greater than 10.

This audio amplifier circuit can be powered from a wide input voltage range from 6 volt up to 24 volts .
For this audio power amplifier circuit diagram you must use a 8 ohms speaker .
