WebMOSFETs are too noisy for many precision amplifier applications. If you have a low impedance source, for the lowest noise of any available monolithic amplifier, you need to go to a bipolar amplifier such as the LT1028 which has a white noise spectral density of 1.1nV/sqrt(Hz). (If that's not good enough, a discrete design can do better).

WebA converter that is used to change the analog signal to digital is known as an analog to digital converter or ADC converter. This converter is one kind of integrated circuit or IC that converts the signal directly from continuous form to discrete form. This converter can be expressed in A/D, ADC, A to D. Webuse a single-ended connection scheme to the ADC. It makes no sense to purchase a fully differential op amp, and then not use the differential output to interface to the differential input of the ADC. In most cases, the dual supply implementation is a trivial change from the single-supply implementation, so schematics may not be included.
