I made a R2-R DAC ladder. In order to test it, i used the generic ADC (8-bit) in the library. My goal was to find if my DAC could correctly sample and filter quantized signal. The maximum input frequency being 20KHz. I kept sampling at 200KHz.
I was unable to simulate this, i tried to trouble shoot the problem but it failed.
P.s I used SPDT switches as i needed to operate the DAC at 10/0 V rather than the TTL 5/0V.
Please advise me how can i tackle this problem.
