Sam&wing · Touch Sensors · SOP-16

AI08 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.
2 C1 passive Internal balance capacitor interface; datasheet recommends a 4.7nF capacitor.
3 CSEL passive Sensitivity adjustment capacitor interface; 0 to 100pF, smaller value gives higher sensitivity, may be left floating.
4 K1 input Touch key input 1, highest priority when multiple keys are pressed.
5 K2 input Touch key input 2.
6 K3 input Touch key input 3.
7 K4 input Touch key input 4.
8 K5 input Touch key input 5.
9 K6 input Touch key input 6.
10 K7 input Touch key input 7.
11 K8 input Touch key input 8, lowest key priority.
12 BCD3 output BCD code output bit 3 (MSB); 1111 means no key pressed, 1011 means sleep calibration mode.
13 BCD2 output BCD code output bit 2.
14 BCD1 output BCD code output bit 1.
15 BCD0 output BCD code output bit 0 (LSB).
16 VDD power_in Positive supply, operating range 2.5 to 5.5V (absolute max -0.3 to 6.0V).
