**Analog Devices** · Voltage References · MSOP-8

ADR3625ARMZ from Analog Devices, in a MSOP-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 | ENABLE | input | The ENABLE pin enables or disables the device, with a logic high input voltage of 1.17 V minimum and a logic low input voltage of 0.63 V maximum. |
| 2 | VIN | power_in | VIN is the input voltage connection, rated for 3 V to 16 V input with a maximum input voltage of 16 V. |
| 3 | GND FORCE | power_in | GND FORCE is the ground connection that carries the load sinking current. |
| 4 | GND SENSE | power_in | GND SENSE is the ground sensing connection and should be connected directly to the GND connection of the load device. |
| 5 | GND | power_in | Pin 5 is a ground pin that must be connected to GND FORCE. |
| 6 | VOUT FORCE | power_out | VOUT FORCE is the reference voltage output, and the output capacitor should be placed as close as possible to this pin. |
| 7 | VOUT SENSE | power_out | VOUT SENSE is the reference voltage output sensing connection and should be connected directly to the voltage input of the load device. |
| 8 | GND | power_in | Pin 8 is a ground pin that must be connected to GND FORCE. |
