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.
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 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.
