amplifier circuit Using 2 W Stereo LM1877
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 .
