TPA2005D1DGNRQ1 from Texas Instruments, in a HVSSOP-8-EP. 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	SHUTDOWN	input	Active-low shutdown terminal; VIH must be at least 2 V and VIL at most 0.7 V with VDD up to 5.5 V.
2	NC	unconnected	No internal connection.
3	IN+	input	Positive differential input.
4	IN-	input	Negative differential input.
5	VO+	output	Positive BTL output driving the speaker.
6	VDD	power_in	Power supply; recommended operating range 2.5 V to 5.5 V, and for the DGN package VDD should be limited to 5 V if short-circuit protection is desired.
7	GND	power_in	High-current ground.
8	VO-	output	Negative BTL output driving the speaker.
9	EP	passive	Exposed pad (from the footprint; not named in the datasheet pin table).
