LSID100
LOW LEAKAGE
PICO-AMP DUAL DIODE
Linear Systems replaces discontinued Intersil LSID100
The LSID100 is a low leakage Monolithic Dual Pico-Amp Diode
The LSID100 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
LSID100 features a leakage current of 0.1 pA and is
well suited for use in applications such as input
protection for operational amplifiers.
LSID100 Benefits:
ƒ Negligible Circuit Leakage Contribution
ƒ Circuit “Transparent” Except to Shunt
High-Frequency Spikes
ƒ Simplicity of Operation
LSID100 Applications:
ƒ Op Amp Input Protection
ƒ Multiplexer Overvoltage Protection

Typical Sample and Hold circuit with clipping. LSID100 diodes
reduce offset voltages fed capacitively from the LSID100 switch
gate.
