LM1875

20W Audio Power Amplifier

General Description

The LM1875 is a monolithic power amplifier offering very low

distortion and high quality performance for consumer audio

applications.

Features

n Up to 30 watts output power

n A_VOtypically 90 dB

n Low distortion: 0.015%, 1 kHz, 20 W

n Wide power bandwidth: 70 kHz

The LM1875 delivers 20 watts into a 4Ω or 8Ω load on 25V

supplies. Using an 8Ω load and 30V supplies, over 30

n Protection for AC and DC short circuits to ground

n Thermal protection with parole circuit

n High current capability: 4A

n Wide supply range 16V-60V

n Internal output protection diodes

n 94 dB ripple rejection

watts of power may be delivered. The amplifier is designed

to operate with a minimum of external components. Device

overload protection consists of both internal current limit and

thermal shutdown.

The LM1875 design takes advantage of advanced circuit

techniques and processing to achieve extremely low distor-

tion levels even at high output power levels. Other outstand-

ing 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 in-

ternally compensated and stable for gains of 10 or greater.

n Plastic power package TO-220

Applications

n High performance audio systems

n Bridge amplifiers

n Stereo phonographs

n Servo amplifiers

n Instrument systems
