LA4814JA
Monolithic Linear IC
2-Channel Power Amplifier
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
