REF195GSZ-REEL from Analog Devices, in a SOIC-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 | TP | unconnected | Test pin reserved for in-package Zener zap trimming; the user should leave Pin 1 unconnected. |
| 2 | VS | power_in | Supply input; the reference holds its output from supplies as low as 100 mV above the output voltage while drawing less than 45 μA of supply current. |
| 3 | SLEEP | input | Sleep mode control; applying a low TTL or CMOS level turns the output off and reduces supply current to less than 15 μA. |
| 4 | GND | power_in | Ground reference pin for the reference. |
| 5 | TP | unconnected | Test pin reserved for in-package Zener zap trimming; the user should leave Pin 5 unconnected. |
| 6 | OUTPUT | output | Voltage reference output (5.00 V nominal for REF195); the device supplies up to 30 mA with short-circuit protection. |
| 7 | NC | unconnected | No connect; not internally connected. |
| 8 | NC | unconnected | No connect; not internally connected. |
