Monolithic Linear IC

LA4814V

2-Channel Power Amplifier

Overview

The LA4814V 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

Features

• On-chip 2-channel power amplifier

Output power 1 = 350mW typ. (V

= 5.0V, R = 4Ω, THD = 10%)

Output power 2 = 150mW typ. (V

= 3.6V, R = 4Ω, THD = 10%)

• Enables monaural BTL output system by changing externally connected components

Output power 3 = 700mW typ. (V

Output power 4 = 320mW typ. (V

• Low-voltage operation possible

• Standby function

= 5.0V, R = 8Ω, THD = 10%)

= 3.6V, R = 8Ω, THD = 10%)

=2.7V and up

Current drain at standby = 0.1μA typ. (V

• Voltage gain setting possible

= 5V)

Voltage gain = 3 to 20dB

• Second amplifier stop control function

Reducing the pop noise at startup (in BTL mode)
