    A very sensitive (10uV/cm) differential amp that also has switchable high- and lowpass filters, and a CMRR of >110dB (!).Very nice, for the sort of applications that require this sort of plugin. For example, you can use this plugin to measure the open loop gain of an audio amp directly, by measuring on the + and - inputs of input stage.
