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). Webdevice is the lowest. This can be seen in Figure 1, where the bipolar OPA2210 (with a quiescent current of 2.2 mA) has lower broadband noise (2.2 nV/rt-Hz) than either 3 nV/rt-Hz in the OPA2156 (CMOS) with an IQ of 4.4 mA, or 4 nV/rt-Hz in the OPA828 (JFET) with an IQ of 5.5 mA. This means that for high-
