Hi

Using PSoC Creator 4.2 schematic designer, there doesn't seem to be a way to connect the DieTemp output connection to a CapSense_ADC input connection, as the CapSense_ADC component doesn't expose any connections in the schematic designer.

It looks as if the CapSense_ADC inputs can only be connected to external pins and not to internal connections.

Therefore, should I connect the DieTemp output to an external pin and then to the CapSense_ADC input pin (possibly the same pin) or is there a better solution?

Thanks

Pete

That is correct, Pete. DieTemp comes with the SAR ADC.

Hello Pete,

DieTemp is designed to be used with the SAR ADC. Is there any specific reason for using CapSense_ADC?

Hi Rajiv

The aim was to find the smallest packaged PSoC available with both CapSense and DieTemp components.

So removing the dependency on using a dedicated ADC component was hopefully going to help achieve this goal.

After look at a range of devices however, it seems that if the device doesn't have a dedicated ADC component it also doesn't have a DieTemp component.

Thanks for your response
