GP8312-TC50-EW from Guestgood, in a SOP-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 | SCLK | input | I2C protocol clock signal input; the I2C input high level is 2.7V-5.5V. |
| 2 | SDA | bidirectional | I2C protocol data signal; the I2C input high level is 2.7V-5.5V. |
| 3 | ALARM | output | Active-low open-drain output-open-circuit alarm; a low level indicates the output (IOUT) is open circuit. |
| 4 | VCC | power_in | Power supply, 18V to 40V (24V typical, 40V maximum). |
| 5 | GND | power_in | Ground; the exposed heat slug must also be grounded. |
| 6 | SET | passive | Full-scale current setting pin, with Rset connected to GND (1k gives 25mA full scale), where full-scale IOUT=5V*5/Rset. |
| 7 | IOUT | output | Analog current output, 4-20mA/0-20mA output port (0-25mA range with Rset = 1k). |
| 8 | V5V | power_out | Internal LDO 5V output; an external 1uF capacitor is required. |
