**Texas Instruments** · Current Sense Amplifiers · VSSOP-8

LMP8480ATQDGKRQ1 from Texas Instruments, in a VSSOP-8. 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, connected to the high side of the current-sense resistor; the common-mode range is 4.0 V to 76 V. |
| 2 | VCC | power_in | Positive supply voltage; the recommended range is 4.5 V to 76 V, and the absolute maximum VCC to GND is 85 V. |
| 3 | NC | unconnected | No connection, not internally connected. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | VOUT | output | Buffered high-current output, specified above 5 mA; the absolute maximum current into the output pin is ±20 mA. |
| 6 | NC | unconnected | No connection, not internally connected. |
| 7 | NC | unconnected | No connection, not internally connected. |
| 8 | RSN | input | Negative current-sense input, connected to the low side of the current-sense resistor; the absolute maximum voltage to GND is 85 V. |
