This is a Getting Started Video for PSoC Designer IDE. The video shows how to create a PSoC project to measure an analog signal and display the result on the LCD and also to configure a 16 bit PWM for a 1Hz output to blink an LED. The project is tested using the CY3210 evaluation board from Cypress.  Watch the video below...

Question:  When I change the input to a Delta Sigma ADC, the result is corrupted.  What is the reason for this?  What are the various factors to be considered while multiplexing the input to a Delta Sigma ADC?

Answer: The Delta Sigma ADC is a pipe-lined ADC.  The output is valid only on the second ADC result.  If there is no change in the input signal, all the subsequent results are valid.

DNL and INL Errors in an ADC

Question: What are DNL and INL Errors in an ADC?  Is there anyway to compensate these errors?

Answer:

DNL - Differential Non-Linearity: For an ideal ADC the output is divided into 2 power n uniform steps each with the width Δ. Any deviation from the ideal step width is the Differential Non-Linearity (DNL). It is expressed as counts. DNL is a function of each ADC's particular architecture.
