Re: Super fast ADC with Esp32

Sampling faster has the advantage of allowing you to filter the results and so get a higher number of effective bits from the ADC. But you also need to pay attention to what effect that has on the signal. At what point does switching nose (ADC Shifting from input 1 to input 2) become noticeable? Th...

Re: Super fast ADC with Esp32

...What microphone do you use that has a frequency response that goes up to 1MHz? Aside from that, you might want to look into I2S. You have 2 I2S channels to which you can connect a stereo codec, for 4 microphones in total. Thank you, I will look into that if I2S might be better for my needs. I mi...

Super fast ADC with Esp32

Hi! I am currently working on a project that needs super fast ADC to sample data from analogue sources. I have currently made a pcb using the TI ADC128S102 and with that I can achive a samplingrate at almost 12Bit/200kHz reading 2 inputs. But... that is not as fast as I would like it to be and the g...
