# LMV551MG

**Texas Instruments** · Operational Amplifier · SC-70-5

LMV551MG from Texas Instruments, in a SC-70-5. 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 amplifier input; the input/output pin voltage must stay between V- − 0.3 V and V+ + 0.3 V (absolute maximum ratings). |
| 2 | V- | power_in | Negative power supply pin; the total supply (V+ − V−) must be between 2.7 V and 5.5 V (recommended operating range, 6 V absolute maximum). |
| 3 | -IN | input | Inverting amplifier input; the input/output pin voltage must stay between V- − 0.3 V and V+ + 0.3 V (absolute maximum ratings). |
| 4 | OUT | output | Amplifier output; the input/output pin voltage must stay between V- − 0.3 V and V+ + 0.3 V (absolute maximum ratings). |
| 5 | V+ | power_in | Positive power supply pin; the total supply (V+ − V−) must be between 2.7 V and 5.5 V (recommended operating range, 6 V absolute maximum). |

## CAD (KiCad official)

- Symbol: `LMV551MG`
- Footprint: `Package_TO_SOT_SMD:SOT-353_SC-70-5`
- 3D model: SC-70-5 (KiCad packages3D, STEP)
- 3D model files: `lmv551mg-etched.step` / `lmv551mg-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lmv551mg.step` / `lmv551mg.glb` are the bare package body.
