XL386 from XINLUDA, in a SOP-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 a capacitor or series R-C between pins 1 and 8 raises the gain up to 200 (46 dB). |
| 2 | -INPUT | input | Inverting input, referenced to ground and internally biased to ground through a 50 kΩ resistor, with input bias current of about 250 nA. |
| 3 | +INPUT | input | Noninverting input, referenced to ground and internally biased to ground through a 50 kΩ resistor, with input bias current of about 250 nA. |
| 4 | GND | power_in | Ground reference for the input and the device. |
| 5 | VOUT | output | Amplifier output, automatically biased to half the supply voltage. |
| 6 | VS | power_in | Power supply voltage input, specified from 4 V to 12 V, with a local decoupling capacitor to GND recommended close to the pin. |
| 7 | BYPASS | output | Bypass decoupling path, to be decoupled with an external capacitor as shown in the typical applications. |
| 8 | GAIN | passive | Gain setting pin paired with pin 1: bypassing the internal 1.35 kΩ resistor with a capacitor between pins 1 and 8 raises the gain to 200, and a series resistor with that capacitor sets any gain from 20 to 200. |
