LMV641MFX from Texas Instruments, 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 | VOUT | output | Rail-to-rail output capable of sourcing 22 mA and sinking 25 mA, with voltage swing 38-58 mV from supply rails (2 kΩ load, 2.7 V supply, 25 °C). |
| 2 | V- | power_in | Negative power supply input; ground in single-supply operation or negative voltage in dual-supply operation. |
| 3 | VIN+ | power_in | Non-inverting input with common-mode input voltage range 0 V to 1.8 V (at 2.7 V supply), input bias current 75-95 nA (25 °C), maximum differential input voltage ±0.3 V. |
| 4 | VIN- | power_in | Inverting input with common-mode input voltage range 0 V to 1.8 V (at 2.7 V supply), input bias current 75-95 nA (25 °C), maximum differential input voltage ±0.3 V. |
| 5 | V+ | power_in | Positive power supply input accepting 2.7 V to 12 V range with typical quiescent current 138 µA at 25 °C. |
