The DPAD2 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 DPAD2 features a leakage current of -2 pA

and is well suited for use in applications such as input

protection for operational amplifiers.

DPAD2 Benefits:



Negligible Circuit Leakage Contribution



Circuit “Transparent” Except to Shunt

High-Frequency Spikes



Simplicity of Operation

DPAD2 Applications:



Op Amp Input Protection



Multiplexer Overvoltage Protection
