LSDPAD20
LOW LEAKAGE
PICO-AMP DUAL DIODE
Linear Systems replaces discontinued Siliconix LSDPAD20
The LSDPAD20 is a low leakage Monolithic Dual Pico-Amp Diode
The LSDPAD20 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 LSDPAD20 features a leakage current of -
20 pA and is well suited for use in applications such as
input protection for operational amplifiers.
LSDPAD20 Benefits:
 Negligible Circuit Leakage Contribution
 Circuit âTransparentâ Except to Shunt
High-Frequency Spikes
 Simplicity of Operation
LSDPAD20 Applications:
 Op Amp Input Protection
 Multiplexer Overvoltage Protection
