Product Description
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.
