DPAD2
LOW LEAKAGE
PICO-AMP DUAL DIODE
Linear Systems replaces discontinued Siliconix DPAD2
The DPAD2 is a low leakage Monolithic Dual Pico-Amp Diode
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:
ï§ Negligible Circuit Leakage Contribution
ï§ Circuit âTransparentâ Except to Shunt
High-Frequency Spikes
ï§ Simplicity of Operation
DPAD2 Applications:
ï§ Op Amp Input Protection
ï§ Multiplexer Overvoltage Protection
