ADR3512WCRMZ-R7 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 shuts the device down when at or below 0.7 V and makes it operational at 0.85 × VIN or higher; tie to VIN for continuous operation. |
| 2 | GND SENSE | power_in | Ground voltage sense connection that must be connected directly to the point of lowest potential in the application. |
| 3 | GND FORCE | power_in | Ground force connection that can be tied to GND SENSE when Kelvin connections are not needed. |
| 4 | DNC | unconnected | Do not connect to this pin. |
| 5 | DNC | unconnected | Do not connect to this pin. |
| 6 | VOUT FORCE | power_out | Reference voltage output (1.2 V nominal) that can source up to +10 mA and sink up to −3 mA. |
| 7 | VOUT SENSE | power_out | Reference voltage output sensing connection that should be connected directly to the voltage input of the load devices. |
| 8 | VIN | power_in | Input voltage connection with a specified range of 2.3 V to 5.5 V and an absolute maximum supply of 6 V. |
