Overview

The LA4450 is a single package two channel power IC

that supports an operating voltage of 26 V. It is partic-

ularly well suited for use as the bus or track power IC in

car stereo applications. Additionally, since the LA4450

can drive 4

Ω 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.

Functions

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