**Guestgood** · ADCs/DACs - Special Purpose · SOP-8

GP9301B-F4K-L2H1-SW 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 | NC | unconnected | No connect; left floating. |
| 2 | NC | unconnected | No connect; left floating. |
| 3 | VIN | power_in | Input for 0-10V analog voltage, PWM signal (high level >2.7V) or 100K resistor, with an internal 100uA pull-up current source. |
| 4 | VCC | power_in | Power supply, 10V to 40V operating range. |
| 5 | GND | power_in | Ground. |
| 6 | PWM | output | PWM duty-cycle output, 0%-100% duty with 5V high level, DPWM = VIN/10V. |
| 7 | PWMB | output | Complementary (inverted) PWM output of the PWM pin, 5V high level. |
| 8 | V5V | power_out | Internal LDO 5V output, requires an external 4.7uF-22uF capacitor (22uF gives best noise immunity), drive capability 10mA. |
