AI08B SOP16 from Sam wing, in a SOP-16. 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 pin (电源地) for the 8-channel capacitive touch sensor. |
| 2 | C1 | passive | Internal balance capacitor interface; datasheet specifies a 4.7 nF capacitor with 10% tolerance (NPO recommended), placed as close to the IC as possible. |
| 3 | CSEL | passive | Sensitivity-setting capacitor interface; smaller capacitance gives higher sensitivity, selectable from 0 pF up to 100 pF, and may be left floating. |
| 4 | K1 | input | Touch key 1 sense input; highest priority when multiple keys are pressed at once. |
| 5 | K2 | input | Touch key 2 sense input; priority decreases from K1 to K8 when multiple keys are pressed. |
| 6 | K3 | input | Touch key 3 sense input; priority decreases from K1 to K8 when multiple keys are pressed. |
| 7 | K4 | input | Touch key 4 sense input; priority decreases from K1 to K8 when multiple keys are pressed. |
| 8 | K5 | input | Touch key 5 sense input; priority decreases from K1 to K8 when multiple keys are pressed. |
| 9 | K6 | input | Touch key 6 sense input; priority decreases from K1 to K8 when multiple keys are pressed. |
| 10 | K7 | input | Touch key 7 sense input; priority decreases from K1 to K8 when multiple keys are pressed. |
| 11 | K8 | input | Touch key 8 sense input; lowest priority when multiple keys are pressed at once. |
| 12 | BCD3 | output | BCD code output bit 3; the BCD outputs read 1111 when no key is pressed. |
| 13 | BCD2 | output | BCD code output bit 2; outputs encode the single active key (K1 = 0000 through K8 = 0111). |
| 14 | BCD1 | output | BCD code output bit 1; outputs encode the single active key (K1 = 0000 through K8 = 0111). |
| 15 | BCD0 | output | BCD code output bit 0; outputs encode the single active key (K1 = 0000 through K8 = 0111). |
| 16 | VDD | power_in | Positive supply; the datasheet gives an operating range of 2.5 V to 5.5 V and an absolute maximum of -0.3 V to 6.0 V. |
