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.
Features
? Preamplifier has a high open-loop gain (VGO = 73 dB).
? Preamplifier requires no NF capacitor.
? Virtual ground capacitor can be 1 μF or less. (Lower impedance is achieved by having a VREF amplifier built in.)
? Ripple filter requires no capacitor for preventing oscillation.
? Powerful output is obtained in low boost output (Po = 21 mW/VCC = 1.2 V, f = 100 Hz).
? A high-frequency cutoff capacitor is built into the preamplifier and power amplifier inputs; anti-buzz provision.
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
