SL8631XT5 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 terminal; should not be forced more than 0.5V beyond either supply because of reverse-biased ESD diodes to each supply. |
| 2 | -VS | power_in | Negative supply terminal, typically ground; may be a voltage other than ground as long as VS+ to VS- stays between 2.1V and 5.5V, and if not grounded it should be bypassed with a 0.1µF capacitor placed close to the part. |
| 3 | +IN | input | Positive (non-inverting) input with a voltage range from (VS- - 0.1V) to (VS+ + 0.1V). |
| 4 | -IN | input | Negative (inverting) input with a voltage range from (VS- - 0.1V) to (VS+ + 0.1V). |
| 5 | +VS | power_in | Positive supply terminal, 2.1V to 5.5V, with a 0.1µF bypass capacitor placed as close to the device as possible. |
