Hi.
My customer use CapSense.
When my customer touch the CapSense button, raw count becomes maximum and I cannot understand the correct Signal.
What could be the cause?
Fsw:6000kHz
Scan resolution : 12bit
Modulator IDAC : 6 (auto - calibration)
Tuning mode : Manual
Best Regards.

Asanuma-san,
The RAW count calculation formula is as follows.
Single IDAC Sourcing mode:
Dual IDAC Sourcing mode:
- Increase the values of Imod and Icomp.
- Decrease the value of Vref, Fsw, and resolution.
The RAW count is reduced by the above two points.
When it comes to sensitivity,
I think the scanning speed and filters will also have an effect.
Regards,
