The MAX44250 is a 20V, ultra-precision, low-noise, low-drift operational amplifier that utilizes patented auto-correlating zeroing techniques to achieve near-zero DC offset and drift. This method continuously measures and compensates for input offset, effectively eliminating 1/f noise and drift over time and temperature. It features a rail-to-rail output stage and operates from a single 2.7V to 20V supply or dual ±1.35V to ±10V supplies. The device consumes 1.15mA of quiescent current while providing a low 5.9nV/√Hz input-referred voltage noise and a 10MHz gain-bandwidth product. It includes an integrated EMI filter to reduce radio frequency interference and is unity-gain stable.
