U401 SERIES
N-Channel JFETs
The U401 Series of high-performance monolithic dual JFETs features extremely low noise, tight offset voltage and drift over temperature specifications. It is targeted for use in a wide range of precision instrumentation applications. The U401 Series has a wide selection of both offset and drift specifications with the prime device, the U401, featuring 5 mV offset and 10 fJ.V/oC drift. The six devices allow designers to make important cost/benefit decisions. This series is available in a TO-?1 hermetically sealed package and is available with military screening. (See Section 1.)
