GONGMOSEMI · Voltage Reference · SO-8
GM7400ARZ-5-R7 from GONGMOSEMI, in a SO-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 | NC | unconnected | No internal connection; the datasheet says to leave this pin floating in the application. |
| 2 | VIN | power_in | Power supply input with a stated supply range of 3.5 V to 40 V, and an absolute maximum input voltage of 45 V. |
| 3 | TEMP | output | Temperature monitor pin that outputs an unbuffered PTAT voltage of 657 mV typical with a temperature sensitivity of 2.2 mV/°C. |
| 4 | GND | power_in | Ground reference pin for the device. |
| 5 | TRIM | input | Output voltage trim pin used to fine-tune VOUT, with an adjustment range listed as ±3 ±6 % for a 10 kΩ potentiometer. |
| 6 | VOUT | power_out | Reference voltage output, which for the 5 V variant is 5 V with an output current of +/-10 mA and built-in short-circuit protection. |
| 7 | NC | unconnected | No internal connection; the datasheet says to leave this pin floating in the application. |
| 8 | NC | unconnected | No internal connection; the datasheet says to leave this pin floating in the application. |
