Product Descriptions
This new breed of amplifier has ultralow offset,drift,and bias current.The AD8628/AD8629 are wide bandwidth auto-zero amplifiers featuring rail-to-rail input and output swings and low noise.Operation is fully specified from 2.7 V to 5 V single supply (±1 .35 V to ±2 .5 V dual supply).
The AD8628/AD8629 provide benefits previously found only inexpensive auto-zeroing or chopper-stabilized amplifiers.Using Analog Devices’new topology,these zero-drift amplifiers combine low cost with high accuracy and low noise. (No external capacitor is required.) In addition,the AD8628/AD8629 greatly reduce the digital switching noise found in most chopper-stabilized amplifiers.
With an offset voltage of only 1 µV,drift of less than
0.005 µV/°C,and noise of only 0.5 µV p-p (0 Hz to 10 Hz), the AD8628/AD8629 are perfectly suited for applications in which error sources cannot be tolerated.Position and pressure sensors,medical equipment,and strain gage amplifiers benefit greatly from nearly zero drift over their operating temperature range.Many systems can take advantage of the rail-to-rail input and output swings provided by the AD8628/AD8629 to reduce input biasing complexity and maximize SNR.
The AD8628/AD8629 are specified for the extended industrial temperature range (−40°C to +125°C).The AD8628 is available in tiny TSOT-23,SOT-23,and the popular 8-lead narrow SOIC plastic packages.The AD8629 is available in the standard 8-lead narrow SOIC and MSOP plastic packages.
