MAX44252

EVALUATION KIT AVAILABLE MAX44250/MAX44251/MAX44252 20V, Ultra-Precision, Low-Noise Op Amps General Description The MAX44250/MAX44251/MAX44252 are 20V, ultraprecision, low-noise, low-drift amplifiers that offer nearzero 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. These single, dual, and quad devices feature rail-to-rail outputs, operate from a single 2.7V to 20V supply, and consume only 1.15mA per channel, while providing 5.9nV/√Hz input- referred voltage noise. The ICs are unity-gain stable with a gain-bandwidth product of 10MHz. With excellent specifications such as offset voltage of 6µV (max), drift of 19nV/°C (max), and 123nVP-P noise in 0.1Hz to 10Hz, the ICs are ideally suited for applications requiring ultra-low noise and DC precision such as interfacing with pressure sensors, strain gauges, precision weight scales, and medical instrumentation.
