ID100_TO-78 Datasheet, PDF (1/1 Pages) Micross Components – a low leakage Monolithic Dual Pico-Amp Diode

ID100
LOW LEAKAGE
PICO-AMP DUAL DIODE
Linear Systems replaces discontinued Intersil ID100
The ID100 is a low leakage Monolithic Dual Pico-Amp Diode
The ID100 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 ID100
features a leakage current of 0.1 pA and is well suited
for use in applications such as input protection for
operational amplifiers.
ID100 Benefits:
ƒ Negligible Circuit Leakage Contribution
ƒ Circuit “Transparent” Except to Shunt
High-Frequency Spikes
ƒ Simplicity of Operation
ID100 Applications:
ƒ Op Amp Input Protection
ƒ Multiplexer Overvoltage Protection
