Using the DAC, ADC and amplifier on the Spartan 3A Starters Kit Board
I am using the Digital-to-Analog Converter, Analog-to-Digital Converter, and Amplifier components on the Spartan 3A board. First, I use the DAC, then I set the Amplifier, and lastly I use the ADC. This sequence of operation occurs 4096 times.
Do I have to set the Amplifier's gain every time I am going to use the ADC or just one time at the beginning?
Does the board contains test voltage pins to connect as inputs to the ADC and verify if it is operating correctly?
