This new family of amplifiers has ultralow offset, drift and bias current. The AD8551, AD8552 and AD8554 are single, dual and quad amplifiers featuring rail-to-rail input and output swings. All are guaranteed to operate from +2.7 V to +5 V single supply. The AD855x family provides the benefits previously found only in expensive autozeroing or chopper-stabilized amplifiers. Using Analog Devices' new topology these new zero-drift amplifiers combine low cost with high accuracy. No external capacitors are required. With an offset voltage of only 1 mV and drift of 0.005 mV/°C, the AD8551 is perfectly suited for applications where 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 AD855x family make both high-side and lowside sensing easy.
The AD855x family is specified for the extended industrial/ automotive (40°C to +125°C) temperature range. The AD8551 single is available in 8-lead MSOP and narrow 8-lead SOIC packages. The AD8552 dual amplifier is available in 8-lead narrow SO and 8-lead TSSOP surface mount packages. The AD8554 quad is available in narrow 14-lead SOIC and 14-lead TSSOP packages.
