... It is guaranteed to operate from single supply as well as from ±15 V dual supplies. The ADA4091 family of op amps features a unique input stage that allows the input voltage to exceed either supply safely without any phase inversion or latch-up; this is called over- voltage protection, or OVP ...

... Evaluate each application carefully to make sure that the increase in current does not affect performance. OUTPUT STAGE The output stage in the ADA4091-2 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 46. DIAC Transfer Characteristic For a worst-case design analysis, consider two cases. The ADA4091-2 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 44. Therefore, two conditions have to be considered to determine which one is the limiting factor. • ...
