Relation between resolution and sampling rate of an ADC

[GiridharYadav]

Dear sir, Is there any relation between the resolution and the sampling rate of an ADC. If so please explain it in detail. If I use NI 9237 Module for the acquisition of signal from load cell, then what is the minimum time required by it to acquire one sample.If the sampling rate is 50KS/s and resolution is 24 bit, how will you caculate the minimum time required by it to acquire one sample. Please explain it in detail. According to my knowledge it would take 20microseconds. Is this is correct? Will this resolution also plays a role in that time? Thanks and Regards A.Giridhar yadav

Hi Giridhar,

For 9237, resolution is fixed to 24 bits and doesn't not effect by sampling rate.

Therefore, you can measure up to 1/50k=20us time between sample at 24 bits with 9237.
