Preamplifier + Power Amplifier
for 3V Headphone Stereos
Overview
The LA4581MB is an auto reverse-supported preamplifier +
power amplifier IC that is intended for use in 3V headphone
stereos.
Features
.
Preamplifier muting and preamplifier output on/off can be
implemented with one pin. This IC can easily be used to
construct a set with a radio.
.
The power amplifier needs no input/output coupling
capacitor.
.
A high-frequency cut capacitor is connected to the
preamplifier input pin and the power amplifier input pin.
(Anti-buzz provision)
.
Because Vref AMP (r0 =10 ) is built in, the virtual
grounding impedance is about 10
. This eliminates the
need for a large capacitor.
.
8
speaker drivable.
