AI03C ssop10 from Sam wing AI03C ssop10, in a SSOP-10-150mil. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 C1 passive Internal reference (balance) capacitor interface. Connect a 1-10 nF NPO capacitor to GND (4.7 nF recommended). Should be placed close to the IC.
2 CSEL passive Sensitivity-adjust capacitor interface. Connect a 0-100 pF NPO capacitor to GND; smaller value gives higher sensitivity. Should be placed close to the IC.
3 KEY1 input Capacitive touch sensing input for channel 1. Connect to touch pad (typically 3mm-30mm square) through a ~1 kΩ series resistor.
4 KEY2 input Capacitive touch sensing input for channel 2. Connect to touch pad through a ~1 kΩ series resistor.
5 KEY3 input Capacitive touch sensing input for channel 3. Connect to touch pad through a ~1 kΩ series resistor.
6 OUT3 output Open-drain output for KEY3. Pulls low when KEY3 is touched, high-impedance otherwise. Requires an external pull-up resistor (typ. 10 kΩ).
7 OUT2 output Open-drain output for KEY2. Pulls low when KEY2 is touched, high-impedance otherwise. Requires an external pull-up resistor (typ. 10 kΩ).
8 OUT1 output Open-drain output for KEY1. Pulls low when KEY1 is touched, high-impedance otherwise. Requires an external pull-up resistor (typ. 10 kΩ).
9 VDD power_in Positive supply input, 2.5 V to 5.5 V (absolute max 6.0 V). Typical current 394 µA at 3.0 V / 666 µA at 5.0 V; sleep current 7 µA / 11 µA. Datasheet recommends a 20 Ω series resistor from the supply rail and a 100 nF decoupling capacitor to GND.
10 GND power_in Ground (supply return). 0 V reference for all pins.
