MOSFET Power Stage (CB980E)

This circuit provides a good audio power from a signal at least 1 V of amplitude. The MOSFET must be provided with heat radiator and the source to provide at least 2 A. Equivalents to the MOSFETs may be used. Applications include multimedia speakers, audio amplifiers for portable radios, MP3 boxes or headphone sound, etc. The source must have excellent filtration. The input is high impedance. We recommend using speakers of at least 10 W in a speaker.
