SL8581XT5 from Slkor SLKORMICRO Elec, in a SOT-23-5. 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 | OUT | output | Amplifier output. |
| 2 | -VS | power_in | Negative power supply, normally tied to ground. |
| 3 | +IN | input | Non-inverting input of the amplifier, with the same voltage range as -IN (from VS- to VS+). |
| 4 | -IN | input | Inverting input of the amplifier, with a voltage range from VS- to VS+. |
| 5 | +VS | power_in | Positive power supply, specified from 2.3 V to 5.5 V (±1.15 V to ±2.75 V). |
