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 4 Ohm or 8 Ohm load on ±25V supplies. Using an 8
Ohm 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.
