Typical Operating Characteristics (continued)
(VDD = PVDD = SHDN = 3V, PGND = SGND = 0V, C1 = C2 = C3 = 1F, CIN = 1F (1206 case size, X7R dielectric ceramic capacitor),
BM_ = 0V, maximum gain setting = 3.5dB, volume attenuation setting = 0dB (total voltage gain = 3.5dB), BassMax disabled. Load
connected between OUT_ and PGND where specified. THD+N measurement BW = 22Hz to 22kHz. Both channels loaded and driven
in phase. TA = +25°C, unless otherwise noted.)

N.C.
No Connection. Not internally connected.
5
ADD
Slave Address Selection Input. Connect ADD to VDD to set the device slave address to 1010001 or to
PGND to set the device slave address to 1010000.
6PVSS
Charge-Pump Output. Connect to SVSS.
7
SDA
Serial Data Input. Connect a pullup resistor greater than 500
Ω from SDA to PVDD.
9
C1N
Charge-Pump Flying Capacitor Negative Terminal. Connect a 1F capacitor between C1P and C1N.
10
PGND
Power Ground. Connect PGND to SGND at a single point on the PCB near the device.
11
C1P
Charge-Pump Flying Capacitor Positive Terminal. Connect a 1F capacitor between C1P and C1N.
12
SCL
Serial Clock Input. Connect a pullup resistor greater than 500
Ω from SCL to PVDD.
13
PVDD
Charge-Pump and Logic Power-Supply Input. Bypass PVDD to PGND with a 1F capacitor and connect
to VDD. PVDD and VDD are internally connected and should each have a 1F bypass capacitor located
as close to the device as possible.
14
SVSS
Headphone Amplifier Negative Power-Supply Input. Connect to PVSS and bypass with a 1F capacitor
to PGND.
