Question
How is the ADA4530-1 better than its competitors?
Answer
The ADA4530-1 has input bias current that is guaranteed at ±20fA due to measurement limitations of a production environment even though theachievable input bias currents are more than an order of magnitude lower. The input bias current is specified with the same maximum specificationsat both 25oC and 85oC. This yields a 45x advantage in maximum input bias current at 85oC and a 20x advantage out to 125oC as compared to its closestcompetitor. This outstanding input bias current over temperature specification enables customers to minimize any correction/calibration that theymake to their system for temperature variation during operation.
