L-4863 - Dual 2.2W Audio Amplifier Plus Stereo Headphone Function

Datasheet Summary

Description

The UTC L4863 is a dual bridge-connected audio power amplifier.

It combines dual bridge speaker amplifiers and stereo headphone amplifiers on one chip to simplify audio system design.

Features

an externally controlled, low-power consumption shutdown mode, a stereo headphone amplifier mode, and thermal shutdown protection. It also utilizes circuitry to reduce “clicks and pops” during device turn-on. DIP-16 CMOS IC SOP-16 SOP-18 HTSSOP-20.
Pb-free plating product number: L4863L.
