Description

The LA4450 is a single package two channel power IC that supports an operating voltage of 26 V. It is particularly well suited for use as the bus or track power IC in car stereo applications. Additionally, since the LA4450 can drive 4 loads, it can be used effectively in highpower 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.
