XW05B

Sam wing · Touch Sensors · SOP-16

XW05B from Sam wing, in a SOP-16. 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 GND power_in Power ground (negative supply reference).
2 C1 passive Internal balance capacitor connection, 1nF to 10nF with 4.7nF typical.
3 CSEL passive Sensitivity adjustment capacitor connection, 0 to 100 pF, smaller values increase sensitivity.
4 PAD0 input Touch key pad 0 input, floating when unused.
5 PAD1 input Touch key pad 1 input, floating when unused.
6 PAD2 input Touch key pad 2 input, floating when unused.
7 PAD3 input Touch key pad 3 input, floating when unused.
8 PAD4 input Touch key pad 4 input, floating when unused.
9 OUT4 tri_state Channel 4 open-drain output, low when pad 4 pressed and high impedance when released, requires pull-up resistor.
10 OUT3 tri_state Channel 3 open-drain output, low when pad 3 pressed and high impedance when released, requires pull-up resistor.
11 OUT2 tri_state Channel 2 open-drain output, low when pad 2 pressed and high impedance when released, requires pull-up resistor.
12 OUT1 tri_state Channel 1 open-drain output, low when pad 1 pressed and high impedance when released, requires pull-up resistor.
13 OUT0 tri_state Channel 0 open-drain output, low when pad 0 pressed and high impedance when released, requires pull-up resistor.
14 AO output Analog voltage output with 1% accuracy, VDD when no key pressed, 4/16VDD to 8/16VDD for PAD0 to PAD4.
15 NC unconnected No connection, internal floating pin.
16 VDD power_in Positive power supply input, 2.5V to 5.5V operating range.
