The MAX44251/MAX44252 are 20V, ultra-precision, low-noise, low-drift amplifiers that offer 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. These dual and quad devices feature rail-to-rail outputs, oper- ate 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 inter- facing with pressure sensors, strain gauges, precision weight scales, and medical instrumentation. The ICs are available in 8-pin SOT23, 8-pin µMAXM, and 14-pin SOIC packages and are rated over the -40°C to +125°C temperature range.
