GH1321LUA

GoChip Elec Tech Shanghai · Linear Hall Sensors · TO-92S

GH1321LUA from GoChip Elec Tech Shanghai, in a TO-92S. 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 Vcc power_in Supply voltage pin, with the datasheet giving an operating supply range of 3.0 V to 7.5 V for the GH1321 variant.
2 Gnd power_in Ground pin, described in the datasheet only as "低" (low) with no further limit or function stated.
3 Vout output Ratiometric analog output that follows the supply voltage, with output voltage typically spanning 0.1 V to (VCC - 0.1) V (minimum 0.2 V to (VCC - 0.2) V).
