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.

Input Differential Voltage limited to 0.8V (typ) by Diodes LSID100
D1 and D2. Common Mode Input voltage limited by Diodes
LSID100 D3 and D4 to ±15V.
Typical Sample and Hold circuit with clipping. LSID100 diodes
reduce offset voltages fed capacitively from the LSID100 switch
gate.
