2 OUT_L output Left channel output; ±8-kV HBM ESD protected, capable of 25 mW into 32 Ω.
3 GND power_in Ground; signal and power reference.
4 MUTE input Active-low mute control; VIL = 38-43% PVDD, VIH = 57-66% PVDD.
5 VSS power_out Charge pump negative supply output.
6 CN bidirectional Charge pump flying capacitor negative connection.
7 NC unconnected No internal connection.
8 NC unconnected No internal connection.
9 CP bidirectional Charge pump flying capacitor positive connection.
10 VDD power_in Supply voltage; 3.0-3.6 V DC recommended operating range.
11 GND power_in Ground; signal and power reference.
12 GAIN input Gain programming pin; connect resistor to ground for 13 selectable gain values.
13 OUT_R output Right channel output; ±8-kV HBM ESD protected, capable of 25 mW into 32 Ω.
14 -IN_R input Negative input for right channel; single-ended input.
