LA4450 Datasheet PDF - Sanyo Semiconductor

●Overview

●The LA4450 is a single package 2-channel power Amplifier thatsupports 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.
