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
 PO = 12W2 (VCC = 26.4V, RL = 8, THD = 10%)
 PO = 20W2 (VCC = 26.4V, RL = 4, THD = 10%)
 Can drive 4 speakers
 Built-in standby switch
 Minimizes impulse noises
Functions
