... The ability to swing rail-to-rail at both the input and output enables designers to build multistage filters in single-supply systems and to maintain high signal-to-noise ratios. The ADA4091 family of op amps is specified over the extended industrial temperature range of −40°C to +125°C. The ADA4091-2 is part of a growing family low power op amps from Analog Devices, Inc ...

... Evaluate each circuit carefully to make sure that the increase in current does not affect performance. 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, are actually connected with their collectors to the output pin to achieve the rail-to-rail output swing ...

... VOLTAGE (V) Figure 38. DIAC Transfer Characteristic For a worst-case design analysis, consider two cases. The ADA4091-2 has the 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 37. Therefore, two conditions have to be considered to determine which one is the limiting factor. • ...
