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 | RSP | input | Positive current-sense input, which sees the common-mode voltage of 4.0 V to 76 V and must stay at or above 4.0 V for valid output. |+| 2 | VCC | power_in | Positive supply voltage, specified from 4.5 V to 76 V and decoupled to GND with a 0.1 µF capacitor placed close to the pin. |+| 3 | NC | unconnected | No internal connection; the pin is not connected inside the device. |+| 4 | GND | power_in | Ground reference for the device, and the reference for the input common-mode and output voltage limits. |+| 5 | VOUT | output | Buffered voltage output with a maximum of VCC − 250 mV or 13.7 V (whichever is smaller) and an absolute maximum of the lesser of VCC + 0.3 V or +20 V; output source/sink current is rated to 20 mA absolute maximum. |+| 6 | REFB | input | Reference voltage B input that sets the output zero-level together with REFA (LMP8481 only); each VREF pin is limited to VCC or 12 V (whichever is smaller), and the average of the two VREF pins is limited to VCC − 1.5 V or 6 V (whichever is smaller). Tie to GND for a ground-referenced output. |+| 7 | REFA | input | Reference voltage A input that sets the output zero-level together with REFB (LMP8481 only); each VREF pin is limited to VCC or 12 V (whichever is smaller), and the average of the two VREF pins is limited to VCC − 1.5 V or 6 V (whichever is smaller). Tie to GND for a ground-referenced output. |+| 8 | RSN | input | Negative current-sense input, which sees the common-mode voltage of 4.0 V to 76 V and must stay at or above 4.0 V for valid output. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | VSSOP-8 |+| Category | Amplifiers/Comparators |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `LMP8481MMX-H`+- Footprint: `Package_SO:VSSOP-8_2.3x2mm_P0.5mm`+- 3D model: VSSOP-8 (KiCad packages3D, STEP)+- 3D model files: `lmp8481mmx-h-etched.step` / `lmp8481mmx-h-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lmp8481mmx-h.step` / `lmp8481mmx-h.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/lmp8481) (32 pp, sha256 `647bd3a212d2fefb`, retrieved 2026-10-08, tier: lcsc)+- **Datasheet language:** Chinese.
