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.
Features
Two channels in a single package PO = 12W2 (VCC = 26.4V, RL = 8, THD = 10%) PO = 20W2 (VCC = 26.4V, RL = 4, THD = 10%) Can drive 4 speakers Built-in standby switch Minimizes impulse noises
Functions
Standby switch (active on high (+5V) input) On-chip impulse noise protection circuit On-chip thermal protection circuit On-chip overvoltage and surge protection circuits
