This family of amplifiers has ultralow offset, drift, and bias current. The AD8552 are dual amplifiers featuring rail-to-rail input and output swings. All are guaranteed to operate from 2.7 V to 5 V with a single supply.
The AD8552 provide the benefits previously found only in expensive auto-zeroing or chopper-stabilized amplifiers. Using Analog Devices, Inc. topology, these new zero-drift amplifiers combine low cost with high accuracy. No external capacitors are required.
With an offset voltage of only 1 μV and drift of 0.005 μV/°C, the AD8552 are perfectly suited for applications in which error sources cannot be tolerated. Temperature, position and pressure sensors, medical equipment, and strain gage amplifiers benefit greatly from nearly zero drift over their operating temperature range. The rail-to-rail input and output swings provided by the AD8552 make both high-side and low-side sensing easy.
The AD8552 are specified for the extended industrial/auto motive temperature range (−40°C to +125°C). The AD8552 dual amplifier is available in 8-lead narrow SOIC and 8-lead TSSOP surface-mount packages.
