Overview
The LA4589W is a 1.5V stereo headphone preamplifier
and power amplifier IC that provides all the functions of a
complete playback system in a single chip, making it ideal
for battery-powered, portable cassette players.
The LA4589W incorporates a metal/normal-tape equaliza-
tion preamplifier, a power amplifier dual power supply
ripple filters, a reference voltage amplifier that enables
small-value (under 1
F) virtual-earth capacitors to be used,
and a system controller.
The LA4589W features single-pin control bass boost and
forward/reverse playback, an automatic music search
(AMS) function, inputs for an auto-reverse tape mechanism,
a power amplifier mute function, a power switch, and se-
lectable single or dual ripple filter operation.
The LA4589W operates from a 0.95 to 2.2V supply and is
available in 48-pin SQFPs.
