DPAD100
LOW LEAKAGE
PICO-AMP DUAL DIODE
Linear Systems replaces discontinued Siliconix DPAD100
The DPAD100 is a low leakage Monolithic Dual Pico-Amp Diode

diode technology when reverse current (leakage) must
be minimized. In addition the monolithic dual
construction allows excellent capacitance matching per
diode. The DPAD100 features a leakage current of -
100 pA and is well suited for use in applications such as
input protection for operational amplifiers.
