Monolithic Linear IC

1.5-V Preamplifier + Power Amplifier  
for Headphone Stereo Products  
functions.  
• Ripple filter  
Overview  
The LA4592W is a single-chip 1.5-V headphone stereo  
system IC. The LA4592W adds a variety of functions,  
including a switch amplifier (for end product audio quality  
switches, the metal tape switch, and other switches) and an  
AMSS (Automatic Music Search System) function that  
supports blank skipping, to the earlier LA4590W.  
Furthermore, the LA4592W provides even lower no-signal  
time power levels for lower end-product power  
dissipation. In combination with the LA3235W 1.5-V  
record preamplifier IC, the LA4592W can be used to  
implement a record/playback cassette system with just two  
ICs.  
• Low boost function (BTL operation in the low-  
frequency region)  
• Inter-track detection function (Supports AMSS and  
blank skipping)  
• Two switching amplifiers  
• Power switch (standby function)  
Features  
• Virtual ground impedance is reduced by built-in V  
amplifier  
REF  
• No capacitor required for ripple filter oscillation  
prevention.  
• Provides ample output power at low frequencies.  
Functions  
• Stereo preamplifier: supports auto reverse and includes a  
muting function.  
(P = 24 mW, V = 1.2 V, f = 150 Hz)  
O
CC  
• High-frequency cutoff capacitors built into the  
preamplifier and power amplifier inputs to minimize  
buzzing.  
• Stereo power amplifier: Includes OCL and muting
