MAX44251AKA+T

MAX44251AKA+T is an ultra-precision, low-noise, low-drift amplifier that offers near-zero DC offset and drift through the use of patented autocorrelating zeroing techniques. This method constantly measures and compensates the input offset, eliminating drift over time and temperature and the effect of 1/f noise. Applications include strain gauges, pressure transducers, medical instrumentation, precision instrumentation, load cell and bridge transducer amplification.

• High accuracy enables precision signal chain acquisition
