8 years agoDC coupled ADC (HSMC)
I bought a "Terasic Cyclone V GX Starter Kit" and I have to process a analog signal. I bought a "Terasic Highspeed AD/DA Card" and connected it via HSMC. Unfortunatly I realized that the inputs are t...

8 years ago --- Quote Start --- Could you please explain why the input range is 0.5 - 2.5V? --- Quote End --- More exactly 0.65 - 2.65 for the present circuit. Because the input is biased to 1.65 V with an ADC input range of +/- 1 V. According to the AD9248, single ended operation with 0 to 2 V input range can be achieved by biasing VINn to 1 V. The voltage divider has to modified respectively.
