LDC2112: One button SPS recommendations

Part Number: LDC2112

Hi 

If our products have battery life concerns and use one button only.

what is minimum SPS recommend?

How to understanding figure 9 for the scan rate?

  • Hi Alex,

    Can you clarify how you are using the button? Are you using it for force detection, or do you just want to detect whether or not someone has pressed the button? Force detection would require a much higher sample rate than just detecting a simple button press. For a simple button press I suggest at least 5-10 SPS.

    Figure 9 is the scan rate distribution across a sample group of devices. This graph shows that most of these sampled devices sampled slightly slower than the nominal sample rates described in the Scan Rate section. The y-axis is the number of devices within a specific bin.

    Best Regards,
