Monolithic Linear IC

LA4663

Two-Channel 16-W BTL General-Purpose

Audio Power Amplifier

(The startup time can be modified in end products by

using this circuit in conjunction with the muting circuit

described above.)

Overview

The LA4663 is a BTL 2-channel power amplifier IC that

was developed for ease of use in general audio

applications. In addition to providing improvements in a

wide range of electrical characteristics, the LA4663 aims

for improved listenability and an excellent cost-

performance ratio.

• Full complement of built-in protection circuits

(protection from shorting to ground, shorting to V

load shorting, and overheating)

• High audio quality, minimal impulse noise

Applications

Package Dimensions

unit: mm

Radio/cassette players with built-in CD/MD players,

microcomponent stereo systems, active speakers,

electronic musical instruments, and other audio devices.

Features

• Wide operating supply voltage range (V op): 5.5 to

22 V (Certain conditions may apply.)

• High ripple rejection ratio: 60 dB (typical)

• Power: 16 W × 2 (V = 15 V/6Ω),

13 W × 2 (V = 12 V/4Ω), 6.5 W × 2 (V = 9 V/4Ω)

• Built-in signal muting circuit (AC muting) reduces the

number of external components and provides muting

with minimal switching noise.

• Startup circuit with a start time of 0.6 to 0.7 seconds.

The LA4663 provides distortion-free startup, since

output is only generated after the supply voltage reaches

the midpoint at power on.
