ADA4522-1ARMZ-RL

ADA4522-1 is a single channel EMI enhanced, zero drift op-amp with low noise and power, ground sensing inputs, and rail-to-rail output, optimized for total accuracy over time, temperature, and voltage conditions. The wide operating voltage and temperature ranges, as well as the high open-loop gain and very low dc and ac errors make the devices well suited for amplifying very small input signals and for accurately reproducing larger signals in a wide variety of applications. It uses on-chip filtering to achieve high immunity to electromagnetic interference (EMI). Application includes inductance, capacitance, and resistance (LCR) meter/ megohmmeter front-end amplifiers, load cell and bridge transducers, magnetic force balance scales, high precision shunt current sensing, thermocouple/resistance temperature detector (RTD) sensors, programmable logic controller (PLC) input and output amplifiers.
