TDA2822M HEADPHONE AMPLIFIER SCHEMATIC CIRCUIT DIAGRAM

The TDA2822M is a very popular amplifier based on power, as it is used in headphone amp applications as well as in computer amplification.

The writer states that he has good results with 4 ohm or 32 ohm loudspeakers used as headphones amphibious. The high impedance headphones (100 Ohm., 600 Ohm.) Mean that the circuit works perfectly, but the volume is lower

The TDA2822M amplifier circuit is a single source DC from 9v … 15v. The EXE DC input socket that can be operated with DC is a cooling socket F1. There is a 6.3mm jack input socket on the PCB. Note: The TDA2822 model is different. In this circuit, TDA2822 M is used.
