LMH6639MF from Texas Instruments, in a SOT-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 | OUTPUT | output | Rail-to-rail amplifier output that swings to within about 30mV of either supply rail with 110mA linear output current. |
| 2 | V- | power_in | Negative supply (ground in single-supply use); the input common mode range extends 0.2V below this pin. |
| 3 | +IN | input | Non-inverting input of the voltage feedback amplifier, protected by anti-parallel diodes and a series resistor across the inputs. |
| 4 | -IN | input | Inverting input of the voltage feedback amplifier, protected by anti-parallel diodes and a series resistor across the inputs. |
| 5 | SD | input | Shutdown input that disables the amplifier when pulled below a threshold of V+ - 1.67V (±5V supplies), with off-mode supply current of 400μA at 5V. |
| 6 | V+ | power_in | Positive supply; the input common mode range extends to within 1V of this pin and the part is characterized for 3V, 5V and ±5V. |
