LMP8481MMX-H 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, 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. |
