Pinout

Pin	Name	Type	Function
1	3DR+	passive	Right channel non-inverting 3D connection; connect to 3DL+ through C3D+ and R3D+, and the two 3D RC networks must have identical component values in fully differential configuration.
2	INR+	input	Right channel non-inverting input of the fully differential audio input pair; input voltage must stay within -0.3V to VDD + 0.3V (absolute maximum).
3	INR-	input	Right channel inverting input of the fully differential audio input pair; input voltage must stay within -0.3V to VDD + 0.3V (absolute maximum).
4	3DEN	input	3D enable input; set high to enable the 3D effect and set low to disable it, with logic input levels VIH min 1.4V and VIL max 0.4V.
5	INL-	input	Left channel inverting input of the fully differential audio input pair; input voltage must stay within -0.3V to VDD + 0.3V (absolute maximum).
6	INL+	input	Left channel non-inverting input of the fully differential audio input pair; input voltage must stay within -0.3V to VDD + 0.3V (absolute maximum).
7	3DL+	passive	Left channel non-inverting 3D connection; connect to 3DR+ through C3D+ and R3D+.
8	3DL-	passive	Left channel inverting 3D connection; connect to 3DR- through C3D- and R3D-.
9	G1	input	Gain select input 1; together with G0 it selects 6, 12, 18 or 24 dB gain (G1G0 = 00, 01, 10, 11 give 6, 12, 18, 24 dB), with logic input levels VIH min 1.4V and VIL max 0.4V.
10	PVDD	power_in	Speaker power supply pin; supply range is 2.4V to 5.5V for VDD and PVDD.
11	OUTLA	output	Left channel non-inverting class D output, which switches between VDD and GND with a 300kHz nominal switching frequency.
12	OUTLB	output	Left channel inverting class D output, which switches between VDD and GND with a 300kHz nominal switching frequency.
13	PGND	power_in	Power ground pin.
14	SDL	input	Left channel active-low shutdown; connect to VDD for normal operation and to GND to disable the left channel, with logic input levels VIH min 1.4V and VIL max 0.4V.
15	SS/FF	input	Modulation mode select; connect to VDD for spread spectrum mode (switching frequency varies by 30% about 300kHz) or to GND for fixed frequency mode at 300kHz.
16	SDR	input	Right channel active-low shutdown; connect to VDD for normal operation and to GND to disable the right channel, with logic input levels VIH min 1.4V and VIL max 0.4V.
17	GND	power_in	Ground pin; the exposed thermal pad must also be connected to GND.
18	PGND	power_in	Power ground pin.
19	OUTRB	output	Right channel inverting class D output, which switches between VDD and GND with a 300kHz nominal switching frequency.
20	OUTRA	output	Right channel non-inverting class D output, which switches between VDD and GND with a 300kHz nominal switching frequency.
21	PVDD	power_in	Speaker power supply pin; supply range is 2.4V to 5.5V for VDD and PVDD.
22	VDD	power_in	Power supply pin; operating range is 2.4V to 5.5V, with an absolute maximum supply of 6.0V.
23	G0	input	Gain select input 0; together with G1 it selects the 6, 12, 18 or 24 dB gain setting, with logic input levels VIH min 1.4V and VIL max 0.4V.
24	3DR-	passive	Right channel inverting 3D connection; connect to 3DL- through C3D- and R3D-.
25	EP	passive	Exposed pad (from the footprint; not named in the datasheet pin table).
