Monolithic Linear IC

LA4587M

Preamplifier + Power Amplifier

for 1.5 V Headphone Stereos

Overview

Package Dimensions

unit : mm

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.

3102-QFP48D

[LA4587M]

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_REFamplifier 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
