DESCRIPTION

The LM1875 is a monolithic power amplifier offering

very low distortion and high quality performance for

consumer audio applications.

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

on ±25V supplies. Using an 8Ω load and ±30V

supplies, over 30 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 distortion levels even at high output

power levels. 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.
