Pin Descriptions
Pin Name
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.
BYPASS (2)
A 0.1 F 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.
POWER AMP OUT LEFT (3) RIGHT (26)
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.
POWER GND (4)
This pin provides the high current return for the power output stage
MOSFETs and digital circuitry.
LOOP OUT (8, 21) LOOP IN (5, 24)
These pins allow an external signal processor access to the stereo signal.
Please see the Application Information section for more information.
TONE OUT
(6, 23)
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.
TONE IN
(7, 22)
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.
INPUTS
(9, 20)
These pins are the stereo inputs for the LM4832. These pins should be
AC-coupled to the input signals.
ANALOG GND (10)
This pin is the AC analog ground for the line level AC signal inputs.
MIC INPUTS (11, 12)
These pins are the two independent selectable microphone inputs. These
pins should be AC-coupled.
MIC OUT (14)
This pin is the output for the microphone amplifier and should be
AC-coupled to the load.
V
DD
(13, 25)
These pins are for the 5V supply. These pins should be separately
bypassed by 0.1 F, or higher, film capacitors. The 5V supply should be
bypassed by a 10 F, or higher, tantalum or aluminum electrolytic
capacitor.
ADDRESS BITS (15, 16)
These pins are used to determine the I
2C address for the LM4832.
CLOCK (17)
This pin is the input for the I
2C clock signal.
DATA (18)
This pin is the input for the I
2C data signal.
GENERAL PURPOSE OUTPUT (19)
This pin provides a general purpose TTL/CMOS output. Please refer to
the Application Information section for more information.
RESET (27)
This pin is a TTL/CMOS input which is used to reset the chip logic and
states.
