LM1875

LINEAR INTEGRATED CIRCUIT

20W AUDIO POWER AMPLIFIER

ꢀ

DESCRIPTION

The UTC LM1875 is a monolithic power amplifier offering very

low distortion and high quality performance for consumer audio

TO-220-5

applications. It delivers 20W into a 4Ω or 8Ω load on ±25V supplies.

Using an 8Ω load and +30V supplies, over 30W 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 UTC LM1875 design utilizes 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.
