LOW LEAKAGE
PICO-AMP DUAL DIODE
Linear Systems replaces discontinued Siliconix DPAD20
The DPAD20 is a low leakage Monolithic Dual Pico-Amp Diode
The DPAD20 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 DPAD20 features a leakage current of -20
pA and is well suited for use in applications such as
input protection for operational amplifiers.
DPAD20 Benefits:
Negligible Circuit Leakage Contribution
Circuit “Transparent” Except to Shunt
High-Frequency Spikes
Simplicity of Operation
DPAD20 Applications:
Op Amp Input Protection
Multiplexer Overvoltage Protection
