Hot selling One stop electronic component supply MAX44250AUK+T Zero-Drift Amplifier 1 Circuit Rail-to-Rail SOT-23-5

Product Descriptions

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 or dual ±1.35V to ±10V supplies 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. 

The ICs are available in 5-pin SOT23, 8-pin SOT23, 8-pin µMAX®, and 14-pin SO packages and are rated over the -40°C to +125°C temperature range.
