LSDPAD1

LSDPAD1 LOW LEAKAGE PICO-AMP DUAL DIODE Linear Systems replaces discontinued Siliconix LSDPAD1 The LSDPAD1 is a low leakage Monolithic Dual Pico-Amp Diode The LSDPAD1 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 LSDPAD1 features a leakage current of -1 pA and is well suited for use in applications such as input protection for operational amplifiers.
