MAX44246AUA+

The MAX44246AUA+ is a low noise, ultra precision dual operational amplifier (op-amp) in 8 pin µMAX package. This low drift op-amp offers near zero DC offset and drift through the use of patented chopper stabilized and auto zeroing techniques. This method constantly measures and compensates input offset by eliminating drift over time and temperature and effect of 1/f noise. Increased accuracy and patented auto zero circuitry eliminates the cost of calibration. The MAX44246 consumes only 0.42mA per channel with only 9nV/√Hz at 1KHz input referred voltage noise. The device is used in transducer amplifiers, load cell, amplifiers, PLC, analogue I/O modules and battery powered equipments.
