LMP8480MME-T

Texas Instruments · Current-Sensing Amplifiers · VSSOP-8

LMP8480MME-T 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, with common-mode voltage range of 4.0 V to 76 V (absolute maximum 85 V to GND).
2 VCC power_in Positive supply voltage, recommended 4.5 V to 76 V (absolute maximum 85 V).
3 NC unconnected No connection; not internally connected.
4 GND power_in Ground.
5 VOUT output Amplifier output, buffered with more than 5 mA drive, limited to the lesser of VCC + 0.3 V or 20 V (absolute maximum).
6 NC unconnected On the LMP8480 this pin is a no connection (it is the reference input only on the LMP8481).
7 NC unconnected On the LMP8480 this pin is a no connection (it is the reference input only on the LMP8481).
8 RSN input Negative current sense input, with common-mode voltage range of 4.0 V to 76 V (absolute maximum 85 V to GND).
