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

ADR3650BRMZ 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 | Enable connection that enables or disables the device; logic high ≥1.17 V enables, low ≤0.63 V shuts down (1.8 V compatible, internal active pull-up, 1.5 µA typical shutdown current). |
| 2 | VIN | power_in | Input voltage connection, specified for 3 V to 16 V operation (absolute maximum 18 V relative to GND SENSE). |
| 3 | GND FORCE | power_in | Ground connection that carries the load sinking current. |
| 4 | GND SENSE | power_in | Ground sensing connection; connect directly to the GND connection of the load device. |
| 5 | GND | power_in | Ground pin to be connected to GND FORCE. |
| 6 | VOUT FORCE | power_out | Reference voltage output (5.000 V typical for ADR3650) requiring 0.1 µF to 10 µF load capacitance, with 70 mA typical sourcing and 20 mA typical sinking capacity. |
| 7 | VOUT SENSE | input | Reference voltage output sensing connection; connect directly to the voltage input of the load device. |
| 8 | GND | power_in | Ground pin to be connected to GND FORCE. |
