Pin Description
LEFT 3D (1)
RIGHT 3D
(28)
An external RC network is connected
across these pins. This function provides
left-right channel cross coupling and
cancellation to create an enhanced
stereo channel separation effect.
A 0.1 μF capacitor is placed between
this pin and ground to provide an AC
ground for the internal half-supply
voltage reference. The capacitor at this
pin affects “click-pop” and THD
performance. Turn-on and turn-off times
are also determined by this capacitor.
Refer to the Application Information
section for more information.
These outputs are intended to drive 8
speakers or 32
headphones. These
outputs should be AC-coupled to the
loads. Refer to the Application
Information section for more information.
This pin provides the high current return
for the power output stage MOSFETs
and digital circuitry.
These pins allow an external signal
processor access to the stereo signal.
Please see the Application Information
section for more information.
These pins are connected to the tone
control op amp outputs and drive the
power amplifier inputs. Refer to the
Application Information section for more
information.
These pins are connected to the inputs
of the tone control op amps. A capacitor
between the Tone In and Tone Out pins
sets the frequency response of the tone
functions. Please refer to the Application
Information section for more information.
These pins are the stereo inputs for the
LM4832. These pins should be
AC-coupled to the input signals.
This pin is the AC analog ground for the
line level AC signal inputs.
These pins are the two independent
selectable microphone inputs. These
pins should be AC-coupled.
This pin is the output for the microphone
amplifier and should be AC-coupled to
the load.
These pins are for the 5V supply. These
pins should be separately bypassed by
0.1 μF, or higher, film capacitors. The 5V
supply should be bypassed by a 10 μF,
or higher, tantalum or aluminum
electrolytic capacitor.
These pins are used to determine the
I

C address for the LM4832.
