DESCRIPTION

The UTC LM1875 is a monolithic power amplifier offering very low distortion and high quality performance for consumer audio applications. It delivers 20W into a 4Ωor 8Ωload on ±25V supplies. Using an 8Ωload 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 limitand thermal shutdown.
