LM1875音频放大器产品详情

DESCRIPTION
The HG LM1875 is a monolithic power amplifier offering very low distortion and high quality performance forconsumer audio applications.
The HG LM1875 delivers 20 wants into a 4 Ω or 8Ω load on ±25V supplies.Using an 8 Ω load and +30Vsupplies,over 30 watts of power may be delivered.The amplifier is designed to operate with a minimumofexternal components.Device overload protection consists of both internal current limit and thernal shutdown.
The HG LM1875 design takes advantage of advanced circuit techniques and processing to achieveextremely low distortion levels even at high output power levels.Other outstanding features include highgain,fast slew rate and a wide power bandwidth,large output voltage swing,high current capability,and a verywide supply range.The amplifier is internally compensated and stable for gains of 10 or greater.
