ph meter +resolution +adc
hello friends , i am interfacing a 16 bit adc with 5 v reference i.e , 5V / 65536 = 76 micro volts , now how do i maintain such a precision in giving analog input of microvolts , my application is a ph meter which reads electrode potential which is then fed to a to d converter 16 bit , how the hardware is to be designed keeping all this in mind.
