LSDPAD50_TO-72 Datasheet, PDF (1/1 Pages) Micross Components – PICO-AMP DUAL DIODE

LSDPAD50
LOW LEAKAGE
PICO-AMP DUAL DIODE
Linear Systems replaces discontinued Siliconix LSDPAD50
The LSDPAD50 is a low leakage Monolithic Dual Pico-Amp Diode
The LSDPAD50 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 LSDPAD50 features a leakage current of -
50 pA and is well suited for use in applications such as
input protection for operational amplifiers.
LSDPAD50 Benefits:
ƒ Negligible Circuit Leakage Contribution
ƒ Circuit “Transparent” Except to Shunt
High-Frequency Spikes
ƒ Simplicity of Operation
LSDPAD50 Applications:
ƒ Op Amp Input Protection
ƒ Multiplexer Overvoltage Protection
