LSID100_TO-78

LSID100 LOW LEAKAGE PICO-AMP DUAL DIODE Linear Systems replaces discontinued Intersil LSID100 The LSID100 is a low leakage Monolithic Dual Pico-Amp Diode The LSID100 low-leakage monolithic dual diode provides a superior alternative to conventional diode technology when reverse current (leakage) must be minimized. In addition the monolithic dual construction allows excellent capacitance matching per diode. The LSID100 features a leakage current of 0.1 pA and is well suited for use in applications such as input protection for operational amplifiers.
