GONGMOSEMI · Voltage Reference · SO-8
GM7400ARZ-10-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; leave floating in the application. |
| 2 | VIN | power_in | Power supply input for the reference, specified at 3.5 V to 40 V in the datasheet's feature list. |
| 3 | TEMP | output | Temperature monitor pin that provides an unbuffered PTAT voltage from the bandgap (657 mV typical, 2.2 mV/°C sensitivity per the electrical table). |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | TRIM | passive | Output voltage trim pin used to adjust VOUT up or down, with an output adjustment range of ±3% typical and ±6% maximum with a 10 kΩ potentiometer. |
| 6 | VOUT | power_out | Buffered reference voltage output, rated for ±10 mA output drive with short-circuit current limit of 30 mA typical. |
| 7 | NC | unconnected | No internal connection; leave floating in the application. |
| 8 | NC | unconnected | No internal connection; leave floating in the application. |
