DPAD5
LOW LEAKAGE
PICO-AMP DUAL DIODE
Linear Systems replaces discontinued Siliconix DPAD5
The DPAD5 is a low leakage Monolithic Dual Pico-Amp Diode
The DPAD5 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 DPAD5 features a leakage current of -5 pA
and is well suited for use in applications such as input
protection for operational amplifiers.
DPAD5 Benefits:
ƒ Negligible Circuit Leakage Contribution
ƒ Circuit “Transparent” Except to Shunt
High-Frequency Spikes
ƒ Simplicity of Operation
DPAD5 Applications:
ƒ Op Amp Input Protection
ƒ Multiplexer Overvoltage Protection
