ANALOG DEVICES MAX4209HAUA+

The MAX4209HAUA+ is an ultra low offset/drift, precision instrumentation amplifier with REF buffer in 8 pin µMAX package. It features exceptional precision specifications, low power consumption, rail to rail output, excellent gain band width product & buffered REFIN/MODE input in a very small package. Device use a spread spectrum, autozeroing technique that constantly measures and corrects input offset, eliminating drift over time and temperature and effect of 1/f noise. This technique achieves less than 20μV offset voltage, allows ground sensing capability, provides ultra low CMOS input bias current and increased common mode rejection performance. It provides high impedance inputs optimized for small signal differential voltages (±100mV) and gain bandwidth product of 750KHz. It is available with a fixed gain of 100V/V with ±0.03% (typ) accuracy. It is used in strain gauge amplifiers, precision low side current sense and differential voltage amplification.
