Analog Devices · Voltage Reference · SOIC-8
REF198GSZ-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 | Factory test point reserved for in-package Zener zap trimming; the user should leave it unconnected. |
| 2 | VS | power_in | Supply input; the output remains stable from supplies as low as 100 mV above the output voltage, with supply current below 45 μA. |
| 3 | SLEEP | input | Sleep control; 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 connection for the device. |
| 5 | TP | unconnected | Test Pin 5 is reserved for in-package Zener zap trimming and must be left unconnected by the user. |
| 6 | OUTPUT | output | Voltage reference output, specified for up to 30 mA of output current and protected against short circuit. |
| 7 | NC | unconnected | No connect; not internally connected. |
| 8 | NC | unconnected | No connect; not internally connected. |
