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.

LSDPAD1 Benefits:

Negligible Circuit Leakage Contribution

Circuit “Transparent” Except to Shunt

High-Frequency Spikes

Simplicity of Operation

LSDPAD1 Applications:

Op Amp Input Protection

Multiplexer Overvoltage Protection

The LSDPAD1 is a low leakage Monolithic Dual Pico-Amp Diode
