**Guestgood** · ADCs/DACs - Special Purpose · ESOP-8L

GP8202S-TC50-EW from Guestgood, in a ESOP-8L. 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; logic high level 2.7V-5.5V. |
| 2 | SDA | bidirectional | I2C protocol data signal; logic high level 2.7V-5.5V. |
| 3 | NC | unconnected | No connection, left floating. |
| 4 | VCC | power_in | Power supply, 9V to 36V (24V typical). |
| 5 | GND | power_in | Ground. |
| 6 | FB | input | Analog current feedback input for the 4-20mA loop, sensed across the Rs resistor for closed-loop current output. |
| 7 | IOUT | output | Analog current output port, 4-20mA output (0-20mA range, 12-bit). |
| 8 | V5V | power_out | Internal LDO 5V output; must be connected to an external 1uF capacitor. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
