Stereo amplifier 2 x 60W Designed by using LM4780 IC .
LM4780 is a superb audio amplifier IC capable of delivering 60W Rms power output / channel into 8 ohm speakers. The LM4780 has very low total harmonic distortion (less than 0.5% at full output) and has a power supply rejection ration (PSRR) of 85 dB.
The IC requires very few external components and has a built in mute facility. The LM4780 is completely protected using their trademark SPiKe technology and has a signal to noise ratio greater than 97dB. The circuit given here is well suitable for applications like components stereos, self powered speakers, home theatre systems, compact stere
- The amplifier can be powered using a 35V DC dual supply.
- Speakers must be 8 ohm, 60W
- An adequately sized heat sink must be fitted to the IC
