LMP8481ATQDGKRQ1

Texas Instruments · Operational Amplifier · VSSOP-8

LMP8481ATQDGKRQ1 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; RSP to GND is rated -0.3 V to 85 V (absolute maximum).
2 VCC power_in Positive supply voltage with a recommended range of 4.5 V to 76 V and an absolute maximum of 85 V (VCC to GND).
3 NC unconnected No connection, not internally connected on the LMP8481-Q1.
4 GND power_in Ground reference for the device.
5 VOUT output Buffered output; the absolute maximum is -0.3 V to the lesser of (VCC + 0.3) or +20 V, with output current limited to 20 mA.
6 REFB input Reference voltage B input (LMP8481-Q1 only); when both VREF pins are tied together the recommended range is -0.3 V to the lesser of (VCC - 1.5) or +6 V.
7 REFA input Reference voltage A input (LMP8481-Q1 only); when both VREF pins are tied together the recommended range is -0.3 V to the lesser of (VCC - 1.5) or +6 V.
8 RSN input Negative current-sense input; RSN to GND is rated -0.3 V to 85 V (absolute maximum).
