LTC8381XT5 from Linearin(先积集成), in a SOT23-5L. 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; the output is short-circuit continuous (ISC is 40 mA source and 50 mA sink through 10 Ω, typical). |
| 2 | -VS | power_in | Negative (lowest) power supply; signal input terminals must stay between VS- - 0.3 V and VS+ + 0.3 V, and VS+ to VS- must not exceed 10.0 V. |
| 3 | +IN | input | Non-inverting input of the amplifier; signal input voltage and current are limited to VS- - 0.3 V to VS+ + 0.3 V and ±10 mA. |
| 4 | -IN | input | Inverting input of the amplifier; signal input voltage and current are limited to VS- - 0.3 V to VS+ + 0.3 V and ±10 mA. |
| 5 | +VS | power_in | Positive (highest) power supply; VS+ to VS- must not exceed 10.0 V (absolute maximum), with operation specified from 1.8 V to 5.5 V. |
