Monolithic Linear IC

For Bus and Track in Car Stereo

LA4450

2-Channel Power Amplifier

Overview

The LA4450 is a single package 2-channel power Amplifier that supports an operating voltage of 26V. It is particularly

well suited for use as the bus and track power IC in car stereo applications. Additionally, since the LA4450 can drive 4Ω

loads, it can be used effectively in high-power high-end products. Furthermore, since it supports a high operating voltage

and has low distortion, it is also optimal for use in TV and home audio products.

Features

Functions

• Two channels in a single package

• Standby switch (active on high (+5V) input)

• On-chip impulse noise protection circuit

• On-chip thermal protection circuit

• On-chip overvoltage and surge protection circuits

• P = 12W×2 (V

= 26.4V, R = 8Ω, THD = 10%)

= 26.4V, R = 4Ω, THD = 10%)

• P = 20W×2 (V

• Can drive 4Ω speakers

• Built-in standby switch

• Minimizes impulse noises
