AI02 from Sam&wing, 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 | GND | power_in | Power ground. |
| 2 | C1 | passive | Internal reference/balance capacitor connection; connect a 4.7nF capacitor (NPO, 10% recommended, placed close to the IC). |
| 3 | KEY1 | input | Touch key 1 sense electrode input, with a 1kΩ series resistor to the sensing pad. |
| 4 | KEY2 | input | Touch key 2 sense electrode input, with a 1kΩ series resistor to the sensing pad. |
| 5 | OUT2 | output | Channel 2 key output; sink current 30 mA min/40 mA typ at VDD=5V, and needs a pull-up resistor when MD is floating. |
| 6 | OUT1 | output | Channel 1 key output; sink current 30 mA min/40 mA typ at VDD=5V, and needs a pull-up resistor when MD is floating. |
| 7 | MD | input | Output mode select: VDD gives direct active-high output, GND gives toggle (latching) output starting low, floating gives active-low output with high-impedance idle. |
| 8 | VDD | power_in | Positive supply, 2.5 to 5.5 V operating range (absolute max 6.0 V). |
