... Evaluate each application carefully to make sure that the increase in current does not affect performance. OUTPUT STAGE The output stage in the ADA4091-x device uses a PNP and an NPN transistor most output stages. However, Q32 and Q33, the output transistors, connect with their collectors to the output pin to achieve the rail-to-rail output swing ...

... VOLTAGE (V) Figure 49. DIAC Transfer Characteristic For a worst-case design analysis, consider two cases. The ADA4091-x has a normal ESD structure from the internal op amp inputs to the supply rails. In addition, it has 42 V DIACs from the external inputs to the rails, as shown in Figure 47. Therefore, two conditions need to be considered to determine which case is the limiting factor. • ...
