55 V, EMI Enhanced, Zero Drift, Ultralow Noise,Rail-to-Rail Output Operational AmplifierKnown Good DieADA4522-2-KGDFEATURESGENERAL DESCRIPTIONLow offset voltage: 5 μV maximum at 5.0 V and 30 V The ADA4522-2-KGD is a dual channel, zero drift op amp with Extremely low offset voltage drift: 22 nV/°C maximum at 30 V low noise and power, ground sensing inputs, and rail - to-rail Low voltage noise density: 5.8 nV/√Hz typical output, optimized for total accuracy over time, temperature, Low peak-to-peak voltage noise: 117 nV p-p from 0.1 Hz to and voltage conditions. The wide operating voltage and 10 Hz typical temperature ranges, as well as the high open-loop gain and Low input bias current: 50 pA typical low dc and ac errors make the device well suited for amplifying Unity-gain crossover: 3 MHz small input signals and for accurately reproducing larger Single-supply operation: input voltage range includes signals in a wide variety of applications. ground and rail-to-rail outputWide range of operating voltages The ADA4522-2-KGD performance is specified at 5.0 V, 30 V, Single-supply operation: 4.5 V to 55 V and 55 V power supply voltages, and the device operates over Dual-supply operation: ±2.25 V to ±27.5 V the 4.5 V to 55 V range. The ADA4522-2-KGD is an excellent Integrated EMI filters selection for applications using single-ended supplies of 5 V Unity-gain stable and 30 V or for applications using higher single supplies and
