LMP8645MKX 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 | Single-ended buffered output with low output impedance, which must stay between V- and V+ per the absolute maximum ratings. |
| 2 | V- | power_in | Negative supply voltage; supply (V+ minus V-) is recommended at 2.7 V to 12 V, with a 13.2 V absolute maximum. |
| 3 | +IN | input | Positive sense input; for the LMP8645 the absolute voltage range is -6 V to 60 V and the differential voltage +IN to -IN is limited to 6 V. |
| 4 | -IN | input | Negative sense input; for the LMP8645 the absolute voltage range is -6 V to 60 V and the differential voltage +IN to -IN is limited to 6 V, with ESD rated at ±5000 V HBM on this pin. |
| 5 | RG | bidirectional | External gain-setting resistor pin, with a 13.2 V absolute maximum voltage rating. |
| 6 | V+ | power_in | Positive supply voltage; supply (V+ minus V-) is recommended at 2.7 V to 12 V, with a 13.2 V absolute maximum. |
