XL386-MS from XINLUDA, in a MSOP-8. 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 | GAIN | passive | Gain setting pin: with pins 1 and 8 open the internal 1.35 kΩ resistor sets the gain to 20 (26 dB), and an external RC between pins 1 and 8 can set the gain up to 200 (46 dB). |
| 2 | -INPUT | input | Inverting input, referenced to ground and biased to ground through an internal 50 kΩ resistor, with the unused input bypassed to ground when higher gains are used. |
| 3 | +INPUT | input | Noninverting input, referenced to ground and biased to ground through an internal 50 kΩ resistor. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | VOUT | output | Amplifier output, automatically biased to half the supply voltage; use short traces to the speaker connection. |
| 6 | VS | power_in | Power supply voltage, specified for 4 V to 12 V (absolute maximum 15 V), with a decoupling capacitor to GND placed close to the pin. |
| 7 | BYPASS | output | Bypass decoupling path for the internal bias node, where a 10 µF bypass capacitor is used in the PSRR specification. |
| 8 | GAIN | passive | Gain setting pin paired with pin 1: an external capacitor between pins 1 and 8 bypasses the internal 1.35 kΩ resistor to raise the gain to 200. |
