Texas Instruments · Current Sense Amplifiers · TSOT-23-6
LMP8640HVMKX-H from Texas Instruments, in a TSOT-23-6. 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 | VOUT | output | Buffered amplifier output, which the datasheet describes as providing low output impedance; its absolute maximum voltage is rated relative to V- and V+ (the rating text is garbled in the extracted datasheet, so verify it against the original PDF). |
| 2 | V- | power_in | Negative supply voltage; the device supply is VS = V+ - V-, with a recommended range of 2.7 V to 12 V. |
| 3 | +IN | input | Positive sense input; the LMP8640HV accepts input common-mode voltage from -2 V to 76 V, and the absolute maximum voltage on +IN/-IN is -6 V to 80 V for the LMP8640HV. |
| 4 | -IN | input | Negative sense input; the differential voltage between +IN and -IN is limited to -6 V to 6 V, and the absolute maximum voltage on this pin is -6 V to 80 V for the LMP8640HV. |
| 5 | NC | unconnected | Not internally connected. |
| 6 | V+ | power_in | Positive supply voltage; the absolute maximum supply voltage (V+ - V-) is 13.2 V and the recommended supply range is 2.7 V to 12 V. |
