Preamplifier + Power Amplifier
for 1.5 V Headphone Stereos
Overview
The LA4587M is a system IC that includes all of the necessary
functions for a playback set on a single chip, reducing the
number of external components needed.
Functions
.
Stereo preamplifier (supports auto reverse function,
switchable between metal and normal tape)
.
Stereo power amplifier (OCL, mute function)
.
Ripple filter
.
Low boost function (BTL operation in low-frequency range)
.
AMSS (Automatic Music Select System)
.
Power switch
Features
.
Preamplifier has a high open-loop gain (VG
O
= 73 dB).
.
Preamplifier requires no NF capacitor.
.
Virtual ground capacitor can be 1 μF or less. (Lower
impedance is achieved by having a V
REF
amplifier built in.)
.
Ripple filter requires no capacitor for preventing oscillation.
.
Powerful output is obtained in low boost output
(Po = 21 mW/V
CC
= 1.2 V, f = 100 Hz).
.
A high-frequency cutoff capacitor is built into the
preamplifier and power amplifier inputs; anti-buzz provision.
