What is Samples averaged of ADC_SAR_Seq

[YoIs_1298666]

Hello,

I have a question.

In ADC_SAR_Seq configuration, there is samples averaged tag. and mimimum value is 2.

Please see the explanation below.

Are the outputs added and averaged ?  For example, in case of PSoC4100S, Does that mean the sample rate is one-half of 1Msps?

Best regards,

Yocchi

When you select a channel for averaging the sampling rate does not change, but it will take two or more (as selected) samples to form a result. Keep in mind that you may switch off the averaging for each channel individually.

Hello Yocchi san,

If you see the channels tab of the ADC configuration

There is an option to enable or disable the sampling rate. For the channels which has enabled summation and averaging will be done. From the component perspective when you have entered the sample rate and try enabling averaging, the component will try to increase the ADC clock accordingly to achieve the required sampling rate. It will throw an error other wise too.
