I want to use the analog MUX of PsOC3 with 32 inputs. How fast will it be to switch the MUX from one input to the next one?
Are you asking now long the MUX actually takes to change the output from one input to another input, or are you asking how long it takes from the change to when the ADC is outputing valid samples of the new input?
many thanks for your answer. I tested to switch 32 analog input pins to one analog output pin. This lasted 1.3ms but it should last less than 300µs. In the real design I want to adc 32 analog inputs in less than 300µs. But at the moment it seems to be impossible with the PsoC. I read that the transistor in PsOC just needs less than 1µs for switching.
In your test project, which component did you use for your MUX? Was it the "AMux" or "AMuxSeq" component? AMuxSeq should be faster than AMux.
