12W FET audio amplifier

12W FET audio amplifier
This is a small 12W power amplifier on a load of 8 Ω, that combining the NE5534 integrated technology with transistors as V-MOSFET output stage get an excellent sound quality. The input sensitivity is 3V rms maximum, the distortion factor is 0.002% at 1 kHz, and frequency response is 15 Hz to 100 kHz. (-3dB). (more…)

80W power amplifier circuit with TDA7294

80W power amplifier circuit with TDA7294
Power Amplifier based tda7294 from ST microeletronics, you can gain power up to 100W in a single chip, for stereo unit, use similar two circuits. This circuit is based on the manufacturer's datasheet for tda7294 typical application usage. Amplifier is ready to work with a powerful signal source, if necessary, use an opamp pre-amplifier. (more…)
