Figure 1. Operational Amplifier Protection
Input Differential Voltage limited to 0.8V (typ) by JPADs D1 and D2. Common
Mode Input voltage limited by JPADs D3 and D4 to ±15V.
Figure 2. Sample and Hold Circuit
Typical Sample and Hold circuit with clipping. JPAD diodes reduce offset
voltages fed capacitively from the JFET switch gate.

1.
Absolute maximum ratings are limiting values above which serviceability may be impaired.
2.
The PAD type number denotes its maximum reverse current value in pico amperes. Devices with IR values intermediate to those shown
are available upon request.
