CAPTIVATE-FR2633: Distance of button for mutual Capacitive for CapTIvate.

Expert 2086 points

My costomer has plan designing PCB for CapTIvate sensor.

In PCB designe. we have some question about button.

Question1 : In Technology Guid designe, Designe allows how close botton to botton distance?

Question2 : In this document designe (P9, Figure6), Designe allows how close botton to botton distance?

Thanks,

Hi GR,

The more close of TX and RX, the lower the detection distance would be.

I would suggest you refer to our EVM board to do the design.

Hi Eason,

I understood that For lower the detection distance, Need more sensor capacitance(To more capacitance ,need to close TX to RX).

Thank you to your support.
