PIN FUNCTIONS  
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 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.  
POWER AMP OUT LEFT (3) RIGHT (26)  
These outputs are intended to drive 8Ω speakers or 32Ω 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)  
MIC INPUTS (11, 12)  
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.  
MIC OUT (14)  
This pin is the output for the microphone amplifier and should be AC-coupled to the  
load.  
VDD  
(13, 25)  
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.  
ADDRESS BITS (15, 16)  
CLOCK (17)  
These pins are used to determine the I2C address for the LM4832.  
This pin is the input for the I2C clock signal.  
DATA (18)  
This pin is the input for the I2C 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.
