LA4814JA

Overview

The LA4814JA buili-in the power amplifier circuit capable of low-voltage (2.7V and up) operation and has additionally a

standby function to reduce the current drain. It is a power amplifier IC optimal for speaker drive used in battery-driven

portable equipment and other such products.

Applications

Mini radio cassette players/recorders, portable radios, transceivers and other portable audio devices
