# LMV651MFX

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

LMV651MFX 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 | +IN | input | Non-inverting input of the amplifier; the datasheet gives no pin-specific voltage limit, so the device common-mode range (0 V to 2.1 V at 3 V supply, per the DC characteristics) applies. |
| 2 | V- | power_in | Negative supply pin (V- = 0 V in the datasheet test conditions); the recommended total supply is 2.7 V to 5.5 V. |
| 3 | -IN | input | Inverting input of the amplifier; the datasheet gives no pin-specific voltage limit, and the absolute maximum input/output voltage is V- − 0.3 V to V+ + 0.3 V. |
| 4 | OUT | output | Amplifier output; the datasheet gives no pin-specific current limit, and the continuous output current is listed as 17 mA source and 25 mA sink, with the note that the part has no short-circuit protection. |
| 5 | V+ | power_in | Positive supply pin; the recommended supply is 2.7 V to 5.5 V and the absolute maximum supply voltage is 6 V. |

## CAD (KiCad official)

- Symbol: `LMV651MFX`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `lmv651mfx-etched.step` / `lmv651mfx-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lmv651mfx.step` / `lmv651mfx.glb` are the bare package body.
