Figure 1. Operational Amplifier Protection
Input Differential Voltage limited to 0.8V (typ) by DPADs D1 and D2. Common
Mode Input voltage limited by DPADs D3 and D4 to ±15V.
Figure 2. Sample and Hold Circuit
Typical Sample and Hold circuit with clipping. DPAD 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 DPAD type number denotes its maximum reverse current value in pico amperes. Devices with IR values intermediate to those
shown are available upon request.
