# LMV641MFE

**Texas Instruments** · Operational Amplifier · SOT-23-5

LMV641MFE 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 | Output of the amplifier, which swings rail-to-rail; output swing is about 40 mV from the supply rail at 2 kΩ load per the datasheet. |
| 2 | V- | power_in | Negative power supply input; with single-supply operation it is tied to ground, and total supply V+ − V- is limited to 2.7 V to 12 V (absolute maximum 13.2 V). |
| 3 | VIN+ | power_in | Non-inverting input; the common-mode input range includes the negative supply rail (0 V to 1.8 V at 2.7 V supply). |
| 4 | VIN- | power_in | Inverting input of the amplifier. |
| 5 | V+ | power_in | Positive power supply input, operating from 2.7 V to 12 V (absolute maximum 13.2 V between V+ and V-). |
