Pin Description
PIN
NAME
FUNCTION
1, 2
OUT+
Positive Speaker Output
3, 16
PVDD
Speaker Amplifier Power-Supply Input. Bypass with a 1F capacitor to ground.
4
BOOT+
Positive Speaker Output Boost Flying-Capacitor Connection. Connect a 0.1F ceramic capacitor
between BOOT+ and OUT+.
5
SCLK
I2C Serial-Clock Input and Modulation Scheme Select. In I2C mode (ADDR1 and ADDR2
≠ GND)
acts as I2C serial-clock input. Connect SCLK to VDD for classic PWM modulation, or connect
SCLK to ground for filterless modulation.
6
SDA/VOL
I2C Serial Data I/O and Analog Volume Control Input
7FB
Feedback. Connect feedback resistor between FB and IN to set amplifier gain. See the Adjustable
Gain section.
8
IN
Audio Input
9, 11
GND
Ground
10
BIAS
Common-Mode Bias Voltage. Bypass with a 2.2F capacitor to GND.
12
SYNC
Frequency Select and External Clock Input.
SYNC = GND: Fixed-frequency mode with fS = 300kHz.
SYNC = Unconnected: Fixed-frequency mode with fS = 360kHz.
SYNC = VDD: Spread-spectrum mode with fS = 300kHz ±7.5kHz.
SYNC = Clocked: Fixed-frequency mode with fS = external clock frequency.
13
SYNCOUT
Clock Signal Output
14
VDD
Power-Supply Input. Bypass with a 1F capacitor to GND.
15
BOOT-
Negative Speaker Output Boost Flying-Capacitor Connection. Connect a 0.1F ceramic capacitor
between BOOTL- and OUTL-.
17, 18
OUT-
Negative Speaker Output
19
SHDN
Shutdown Input. Drive SHDN low to disable the audio amplifiers. Connect SHDN to VDD for normal
operation
20
MUTE
Mute Input. Drive MUTE high to mute the speaker outputs. Connect MUTE to GND for normal
operation.
21, 22
PGND
Power Ground
23
ADDR2
Address Select Input 2. I2C address option, also selects volume control mode.
24
ADDR1
Address Select Input 1. I2C address option, also selects volume control mode.
—EP
Exposed Pad. Connect the exposed thermal pad to GND, and use multiple vias to a solid copper
area on the bottom of the PCB.
