LA6541
4-channel Bridge Driver
for Compact Discs
Overview
The LA6541 is a 4-channel bridge (BTL) driver with a 5 V
power supply (uses an external PNP transistor) developed for
compact discs.
Functions and Features
. 4-channel bridge (BTL) power amplifier.
. IO max. = 700 mA.
. With mute circuit
(Affects all amplifier outputs, Amp 1 to Amp 8).
(When the mute voltage is low, the outputs turn off;
when the mute voltage is high, the outputs turn on).
. 5.0 V regulator built in (Uses external PNP transistor).
. Reset circuit built in (The reset output delay time can be
adjusted through an external capacitor).
