Product Overview This series of amplifiers features ultra-low offset, drift, and bias current. The AD8551, AD8552, and AD8554 are unipolar, bipolar, and quad amplifiers respectively, with rail-to-rail input and output slew rates. All amplifiers are guaranteed to operate from a single supply voltage ranging from 2.7 V to 5 V. The AD8551/AD8552/AD8554 deliver advantages previously found only in costly auto-zero or chopper-stabilised amplifiers. Employing a topology developed by Analog Devices, Inc., these new zero-drift amplifiers combine low cost with high precision. No external capacitors are required. With an offset voltage of just 1 μV and drift of 0.005 μV/°C, the AD8551/AD8552/AD8554 are ideal for applications where error sources cannot be tolerated. Temperature, position, and pressure sensors, medical equipment, and strain gauge amplifiers all benefit from their near-zero drift across the operating temperature range. The rail-to-rail input and output swing provided by the AD8551/AD8552/AD8554 facilitates both high-side and low-side sensing.
