Product Overview

The AD8628ARTZ-REEL7 is a wide bandwidth Auto-zero Amplifier featuring rail-to-rail input and output swing and low noise. Operation is fully specified from 2.7 to 5V single supply (±1.35 to ±2.5V dual supply). The operational amplifier provides benefits previously found only in expensive auto-zeroing or chopper-stabilized amplifiers. In addition, the AD8628 greatly reduce the digital switching noise found in most chopper-stabilized amplifiers. With an offset voltage of only 1μV, drift of less than 0.005μV/°C and noise of only 0.5μVp-p (0Hz to 10Hz), the AD8628 is suited for applications where error sources cannot be tolerated. 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 to reduce input biasing complexity and maximize SNR. The AD8628 is specified for the extended industrial temperature range (-40 to +125°C).
