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). |
