VA2101CSG9

VIVA(昱盛) · Audio Amplifiers · WLCSP-9

VA2101CSG9 from VIVA(昱盛), in a WLCSP-9. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
A1 INP input Positive audio signal input of the differential pair; the datasheet limits its input voltage to 0 to VDD.
C1 INN input Negative audio signal input of the differential pair; the datasheet limits its input voltage to 0 to VDD.
C2 SD_B input Active-low shutdown control; it should be held high during normal operation, and pulling it low or leaving it floating mutes the outputs and puts the amplifier in its low-current state.
C3 OUTP output Positive BTL (bridge-tied load) output, which drives the speaker together with OUTN.
A3 OUTN output Negative BTL (bridge-tied load) output, which drives the speaker together with OUTP.
B1 VDD power_in Power supply pin; the supply range is 2.8 V to 5.5 V and this pin is one of two VDD balls that must be decoupled close to the package.
B2 VDD power_in Power supply pin; the supply range is 2.8 V to 5.5 V and this pin is one of two VDD balls that must be decoupled close to the package.
A2 GND power_in Power ground pin for the amplifier output stage and supply return.
B3 GND power_in Power ground pin for the amplifier output stage and supply return.
