2 x 20Watts, 20watts Power Audio Amplifier
Stereo Hi-Fi Audio Amplifier (LM1875)
The LM1875 is a monolithic power amplifier offering very low distortion and high quality performance for consumer audio applications.
Audio Power Amplifier Based On LM1875 ICs. It has good input And Up to 30 watts output power
*Avo typically 90 dB
*Low distortion: 0.015%,1kHz,20W
*Wide power bandwidth: 70kHz
*Protection for AC and DC short circuits to ground
*Themal protection with parole circuit
*High current capability: 4A
*Wide supply range 16V-30V
*Internal output protection diodes
*94 dB ripple rejection
The LM1875 delivers 20 wants into a 4Ω or 8Ω load on +25V supplies.Using an 8 Ω load and +30V supplies,over 30 watts of power may be delivered.The amplifier is designed to operate with a minimum ofexternal components.Device overload protection consists of both internal current limit and thernal shutdown. Other outstanding features include high gain,fast slew rate and a wide power bandwidth,large output voltage swing,high current capability,and a very wide supply range.The amplifier is internally compensated and stable for gains of 10 or greater.
