GONGMOSEMI · Voltage Reference · SO-8
GM7400BRZ-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 SOIC-8 package. |
| 2 | VIN | power_in | Power supply input, specified for 3.5 V to 40 V operation with a 45 V absolute maximum input voltage. |
| 3 | TEMP | output | Unbuffered temperature-monitor output providing a PTAT voltage of 657 mV typical with 2.2 mV/°C temperature sensitivity per the electrical characteristics table. |
| 4 | GND | power_in | Ground reference pin for the device. |
| 5 | TRIM | passive | Output voltage trim pin used to fine-adjust VOUT; the datasheet gives an adjustment range of ±3 % to ±6 % with a 10 kΩ potentiometer. |
| 6 | VOUT | power_out | Buffered reference voltage output that supports ±10 mA output current with short-circuit current limit of 30 mA typical. |
| 7 | NC | unconnected | No internal connection; the datasheet says to leave this pin floating in the SOIC-8 package. |
| 8 | NC | unconnected | No internal connection; the datasheet says to leave this pin floating in the SOIC-8 package. |
