LM1875
LINEAR INTEGRATED CIRCUIT
20W AUDIO POWER AMPLIFIER
ꢀ
DESCRIPTION
1
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.
