The AD8638ARJZ is an auto-zero single Operational Amplifier with rail-to-rail output swing. This amplifier has very low offset, drift and bias current. Operation is fully specified from 5 to 16V single supply. The AD8638 provides benefits previously found only in expensive zero-drift or chopper-stabilized amplifier. No external capacitors are required. In addition, the AD8638 greatly reduce the digital switching noise found in most chopper-stabilized amplifiers. With a typical offset voltage of only 3μV, drift of 0.01μV/°C and noise of 1.2μVp-p (0.1 to 10Hz), the AD8638 is suited for applications in which error sources cannot be tolerated. Position and pressure sensors and strain gage amplifiers benefit greatly from nearly zero drift over their operating temperature ranges. Many systems can take advantage of the rail-to-rail output swing provided by the AD8638 to maximize signal-to-noise ratio (SNR).
