hello :
I'm designing an oscilloscope by using psoc6. I'm looking for some similar application notes. could you want to share with me ? I saw that the kit has only one ADC and DAC.If I use two channels of ADC, will the sampling rate be reduced to half? And how do I convert the data of 2-channel ADC just with a single DAC? Do I need an external DAC?
Looking forward to receiving your answer.
THANKS!

Hi Peng,
The achieved scan rate of the ADC depends on the following factors,https://www.cypress.com/file/387826/download
▪ ADC clock rate
▪ Number of channels
▪ Averaging
▪ Resolution
▪ Achieved acquisition time
As number of channels is part of it, this will affect the maximum achievable sample rate. Please see the ADC Datasheet.
PSoC6 also has 8-bit and 7-bit resolution IDACs additional to the VDAC. These with a resistor load and opamp buffer can be also used if the resolution is sufficient.
