GM7400BRZ-5-R7

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.
