Product Summary

The LM1875T is an audio power amplifier. The LM1875T is a monolithic power amplifier offering very low distortion and high quality performance for consumer audio applications. The LM1875T 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.
