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.
