I am not sure what this implies; would you be able to build an equivalent, digital circuit (with presumably a ADC and a DAC stage) with an average AVR then? Or what's the clock comparison for?
- raverbashing 7y agoThe unit gain (for an OpAmp at least) is related to the bandwidth, the gain decreases linearly (in the dB scale) as the frequency goes up. You want to be looking at the -3dB range to know +/- the actual useful bandwidth
- theon144 7y agoOkay, but I'm still confused as to why would you compare it to AVR frequency; was that just a random comparison ("this car goes so slow you could outrun it") or would the frequency of a MCU clock being higher than the bandwidth of an op amp ever be important?
- raverbashing 7y agoCorrect, the comparison makes no sense > would the frequency of a MCU clock being higher than the bandwidth of an op amp ever be important Unless you specifically want to capture the analog waveform of the clock signal of that processor, it is unimportant
