SGM4917AYTQ16G from SGMICRO, in a TQFN-16-EP(3x3). 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
1 PVDD power_in Charge-pump power supply that powers the charge-pump inverter, charge-pump logic and oscillator; connect to a 2.7V to 5.5V positive supply and bypass with 1µF to PGND as close to the pin as possible.
2 C1P passive Flying capacitor positive terminal of the charge pump.
3 PGND power_in Power ground for the charge pump; connect to ground.
4 C1N passive Flying capacitor negative terminal of the charge pump.
5 PVSS power_out Charge-pump output that must be connected to SVSS.
6 SGND power_in Signal ground; connect to ground.
7 INR+ input Noninverting right-channel audio input.
8 INR- input Inverting right-channel audio input.
9 SVDD power_in Amplifier positive power supply; connect to a 2.7V to 5.5V positive supply and bypass with 1µF to SGND as close to the pin as possible.
10 OUTR output Right-channel headphone output.
11 SVSS power_in Amplifier negative power supply; connect to PVSS.
12 OUTL output Left-channel headphone output.
13 SVDD power_in Amplifier positive power supply; connect to a 2.7V to 5.5V positive supply (same net as pin 9).
14 INL- input Inverting left-channel audio input.
15 INL+ input Noninverting left-channel audio input.
16 SHDN input Active-low shutdown input.
17 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
