Overview
The LA4450 is a single package two channel power IC
that supports an operating voltage of 26 V. It is partic-
ularly 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 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.
Functions
Standby switch (active on high (+5 V) input)
On-chip impulse noise protection circuit
On-chip thermal protection circuit
On-chip overvoltage and surge protection circuits
