LA4450

Monolithic Linear IC

2-Channel, 26V, Power Amplifier

for Bus and Track in Car Stereo

http://onsemi.com

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 4

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

 Two channels in a single package

 P = 12W2 (V

= 26.4V, R = 8, THD = 10%)

= 26.4V, R = 4, THD = 10%)

 P = 20W2 (V

 Can drive 4 speakers

 Built-in standby switch

 Minimizes impulse noises

Functions

 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
