14 years ago --- Quote Start --- How do i start with the adc? I am not able to find any extensive tutorial ao information on it? It would be great if u could let me know where to start --- Quote End --- You would need to interface to an external analog-to-digital converter to use the analog output of the sensor. There is a technique where you can use an LVDS input as a fast comparator, and then implement a sigma-delta ADC. http://www.latticesemi.com/products/intellectualproperty/referencedesigns/simplesigmadeltaadc.cfm However, the sensor you want to interface to already has digital output options, so why not use them?
