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.

Note 2 - Design reference only, not 100% tested FIGURE 1 – Operational Amplifier Protection 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. FIGURE 2 – Sample & Hold Circuit Typical Sample and Hold circuit with clipping. LSID100 diodes reduce offset voltages fed capacitively from the LSID100 switch gate.
