... XFCB) process. This process includes trench-isolated transistors that lower parasitic capacitance. Figure 26 shows a simplified schematic of the AD8614/AD8644. The input stage is rail-to-rail, consisting of two complementary differential pairs, one NPN pair and one PNP pair. The input stage is protected against avalanche breakdown by two back-to- back diodes. Each input has a 1.5 kΩ ...

... This resistance should be placed in series with either or both inputs if they are subjected to the overvoltages. OUTPUT PHASE REVERSAL The AD8614/AD8644 are immune to phase reversal as long as the input voltage is limited to within the supply rails. Although the device’s output does not change phase, large currents due to input overvoltage can result, damaging the device ...

... When driving heavy capacitive loads directly from the AD8614/AD8644 output, a snubber network can be used to improve the transient response. This network consists of a series R-C connected from the amplifier’s output to ground, placing it in parallel with the capacitive load. The configuration is shown in Figure 28 ...
