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.
Functions
Stereo preamplifier: supports auto reverse and includes a
muting function.
Stereo power amplifier: Includes OCL and muting
functions.
Ripple filter
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
REF
amplifier
No capacitor required for ripple filter oscillation
prevention.
Provides ample output power at low frequencies.
