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).

WebThe Bipolar Junction Transistor (BJT) when used for power switching applications, operates as an IGBT. When it is conducting (BJT operating in the saturated region), a forward … 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.
