DESCRIPTION
Calogic’s ultra low leakage dual pico amp diodes out perform
conventional diodes for applications where reverse current
(leakage) is critical and must be kept at a minimum. The
devices have very low capacitance and are also fast
switching. Housed in a compact dual hermetic package and a
plastic surface mount SO-8 this product is also available in
chip form for hybrid uses.

APPLICATION
Operational Amplifier Protection. Input Differential Voltage
limited to 0.8 V (typ) by DPADS D1 and D2 Common mode
input voltage limited by DPADS D3 and D4 to ±15V.
Typical sample and hold circuit with clipping, DPAD diodes
reduce offset voltages fed capacitively from the FET switch
gate.
