The AD8628ARTZ-R2 is a zero-drift single Operational Amplifier features ultralow offset, drift and bias current. The AD8628 is wide bandwidth low noise auto-zero amplifier has rail-to-rail input and output swing. Using Analog Devices, Inc., topology, this zero-drift amplifier combines high accuracy and low noise. No external capacitor is required. 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 (0 to 10Hz), the AD8628 is suited for applications where error sources cannot be tolerated. Position and pressure sensors 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 to reduce input biasing complexity and maximize SNR.
