Product Summary

The LM1875T is a monolithic power amplifier offering very low distortion and high quality performance for consumer audio applications. The LM1875T 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 LM1875T is designed to operate with a minimum of external components. Device overload protection consists of both internal current limit and thermal shutdown.
