MAX44246ASA+T

MAX44246ASA+T is an ultra-precision, low-noise, low-drift operational amplifier that offers near-zero DC offset and drift through the use of patented chopper stabilized and auto-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 transducer amplifiers, load cell amplifiers, precision instrumentation, battery-powered equipment, PLC analogue I/O, modules.

• Reduces noise-sensitive precision applications, rail-to-rail output
• Low 9nV/√Hz noise at 1KHz, integrated EMI filter
