# LMV851MG

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

LMV851MG 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 input; common-mode range includes ground (−0.2V) up to V+ − 1.2V for best CMRR. |
| 2 | V- | power_in | Negative supply (ground in single-supply use); supply span V+ - V- is 2.7V to 5.5V. |
| 3 | -IN | input | Inverting input of the op amp. |
| 4 | OUTPUT | output | Rail-to-rail output that drives capacitive loads up to 200 pF without an isolation resistor and sources/sinks about 30 mA at 3.3V. |
| 5 | V+ | power_in | Positive supply, 2.7V to 5.5V (absolute maximum 6V), decoupled with a 10 nF capacitor placed close to the pin. |

## CAD (KiCad official)

- Symbol: `LMV851MG`
- Footprint: `Package_TO_SOT_SMD:SOT-353_SC-70-5`
- 3D model: SC-70-5 (KiCad packages3D, STEP)
- 3D model files: `lmv851mg-etched.step` / `lmv851mg-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lmv851mg.step` / `lmv851mg.glb` are the bare package body.
