LSK489 Application NoteLow Noise Dual Monolithic JFETBob CordellIntroductionFor circuits designed to work with high impedance sources, ranging from electrometers to microphone preamplifiers, the use of a low noise, high impedance device between the input and the op amp is needed in order to optimize first glance, one of Linear Systems most popular parts, the LSK389 ultra low noise dual jfet would appear to be a good choice for such an Application . The part s high input impedance (1 T ) and low noise (1 nV/ Hz at 1kHz and 2mA drain current) enables power transfer while adding almost no noise to the signal. But further examination of the LSK389 s specification shows an input capacitance of over 20pF.
