LA4450

Ordering number : EN4090E 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.
