XD386-1 from XINLUDA, in a DIP-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, and a capacitor or series R-C between pins 1 and 8 raises the gain up to 200. |
| 2 | -INPUT | input | Inverting input, referenced to ground through an internal 50 kΩ bias resistor, with about 250 nA input bias current. |
| 3 | +INPUT | input | Noninverting input, referenced to ground through an internal 50 kΩ bias resistor, with about 250 nA input bias current. |
| 4 | GND | power_in | Ground reference for the input and the output bias; the input signal is referenced to this pin. |
| 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 capacitor to GND placed close to the pin. |
| 7 | BYPASS | output | Bypass decoupling path for the internal bias node, typically decoupled with a 10 µF capacitor (per the PSRR test condition). |
| 8 | GAIN | passive | Gain setting pin paired with pin 1; leaving both open gives a gain of 20, and bridging them with a capacitor gives up to 200. |
