LSDPAD10
LOW LEAKAGE
PICO-AMP DUAL DIODE
Linear Systems replaces discontinued Siliconix LSDPAD10
The LSDPAD10 is a low leakage Monolithic Dual Pico-Amp Diode
The LSDPAD10 extremely 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 LSDPAD10 features a leakage current of -
10 pA and is well suited for use in applications such as
input protection for operational amplifiers.
