Adc Pdf Analog To Digital Converter Microcontroller How can i read the datasheet to determine the interval between each acquisition of a voltage by the adc and the time it takes to convert this voltage to an output code?. Conversion time is how long time does it take for convert from analog to digital which it depend on adc resolution. for a single channel you can calculate how many cycle to use by samplingcycle conversioncycle.
Adc Interfacing Pdf Analog To Digital Converter Now, i want to try this function with the pic18f4550, but, looking at the datasheet, the acquisition time seems to be programmable. i'm kind of confused with both time definitions. As you know, we can clearly understand acquisition time and conversion time of a sar adc，which are described in datasheet. but for a given Σ Δ adc or pipeline adc, how to know its acquisition time and conversion time? would you please give me an example to explain these specifications? thanks!. The shortest time between consecutive samples (highest permitted sampling rate) will be the sum of the time needs for each of these phases of acquisition (channel switch, settle, sample, convert). Your total time should be around 30us 10us acquisition time and 20us sampling time. this assumes you only sample one signal, if you switch adc channels then you need to have a longer acquisition time.

Your total time should be around 30us 10us acquisition time and 20us sampling time. this assumes you only sample one signal, if you switch adc channels then you need to have a longer acquisition time. To estimate the maximum achievable sampling rate, you have to compute what is the required acquisition time for your input signals, if you are sampling different channels. I was unable to get the answer by checking the method that you have shared for adc timing, so please explain it to me in detail. in the development, i can't find any power generating ic for 5v to supply to vdd. There are essentially 2 aspects of a d acquisition and conversion. acquisition is the time it takes for the voltage on the a d pin to be "readable ". the charging cap (i think hope that this is internal to the pic) charges to the voltage after some time and then the voltage may be converted. The conversion delay is how long it takes for a measurement to return a value, the acquisition delay is how long it takes for the input amplifier to settle if you change channels or make sudden large changes in input voltage.
