VA2110SPG10 from VIVA(昱盛), in a SOP-10. 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 | SD_B | input | Active-low shutdown control with TTL logic levels referenced to VDD; it should be held high during normal operation, and pulling it low puts the amplifier into a low-current state. |
| 2 | VREG | power_out | Internal regulator output that biases the upper output MOSFET gates, specified at 5.25 V to 6.25 V with 100 µA load over VDD = 6 V to 26 V, and requires at least 1 µF to ground. |
| 3 | INN | input | Negative audio signal input with a typical input impedance of 9 kΩ at the fixed 36 dB gain. |
| 4 | INP | input | Positive audio signal input with a typical input impedance of 9 kΩ at the fixed 36 dB gain. |
| 5 | MUTE | input | Mute input for fast output disable/enable (HIGH = outputs Hi-Z, LOW = outputs enabled), is 5 V TTL compliant, must not be connected to VDD or any source above 5 V, and should not be left floating. |
| 6 | VDD | power_in | Power supply for the amplifier and output transistors, operating from 6.0 V to 26 V with an absolute maximum of 30 V. |
| 7 | OUTP | output | Positive PWM output to the speaker, with a 0.47 µF bootstrap capacitor connected from this pin to BSP. |
| 8 | BSP | bidirectional | Bootstrap I/O for the positive high-side switch, requiring a 0.47 µF ceramic capacitor rated at least 25 V between OUTP and BSP. |
| 9 | BSN | bidirectional | Bootstrap I/O for the negative high-side switch, requiring a 0.47 µF ceramic capacitor rated at least 25 V between OUTN and BSN. |
| 10 | OUTN | output | Negative PWM output to the speaker, with a 0.47 µF bootstrap capacitor connected from this pin to BSN. |
