4522-2

Product Overview

4522-2 is commonly associated with Analog Devices ADA4522-2 series dual-channel zero-drift operational amplifiers, where 4522-2 is often used as a shortened marking-style or listing reference. The device is designed for precision signal conditioning applications requiring low offset voltage, low offset drift, low noise and stable accuracy over time, temperature and supply voltage. With rail-to-rail output, ground-sensing inputs, wide 4.5V to 55V supply operation, EMI-enhanced inputs and compact MSOP / SOIC package options depending on the full ordering code, it is suitable for sensor signal conditioning, precision instrumentation, current sensing, thermocouple measurement, bridge amplifiers, medical equipment and industrial control systems.
