ADR3440ARJZ-R7 from Analog Devices, 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 | GND FORCE | power_in | Ground drive connection for the reference, which carries the device ground return and can be tied to GND SENSE in a standard 3-pin configuration. |
| 2 | GND SENSE | power_in | Ground voltage sense connection that should be connected directly to the lowest potential point in the application for accurate output voltage. |
| 3 | ENABLE | input | Enable pin: pulling it to 0.7 V or lower puts the device in low-power shutdown, 0.85 × VIN or higher enables it, and it should not be held between 0.7 V and 0.85 × VIN. |
| 4 | VIN | power_in | Input voltage connection; the ADR3440 is specified for VIN from 4.3 V to 5.5 V, with an input slew rate of at least 0.1 V/ms recommended. |
| 5 | VOUT SENSE | input | Reference output sense connection that should be connected directly to the voltage input of the load device to maximize output accuracy. |
| 6 | VOUT FORCE | power_out | Reference voltage output, 4.096 V nominal for the ADR3440, capable of sourcing up to 10 mA and sinking up to −3 mA. |
