Seeking Advice on Capacitive Touch Sensing ICs
Hii everyone I hope you had a wonderful day!!! I'm exploring capacitive touch sensing for a new project So plz can anyone share experiences with specific touch sensor ICs and provide insights into best practices for reliable touch interfaces?

I have worked on Infineon series of parts and seen their Capsense which is ultimate. Note that it is MCU integrated in their PSoC series of chips and provides and GUI to configure sensitivity, pattern etc. If you're looking for external IC, check https://www.ti.com/product/FDC2214
opens up quite interesting applications.
an beautiful reference design https://www.ti.com/tool/FDC2214PROXSEN-EVM (this actually matters alot - getting the design right just like PCB antennas)...
