The AD8629ARZ is a zero-drift, single-supply, rail-to-rail input/output Operational Amplifier. It has ultralow offset, drift and bias current. It is a wide bandwidth auto-zero amplifier featuring rail-to-rail input and output swing and low noise. It provides benefits previously found only in expensive auto-zeroing or chopper-stabilized amplifier. Using Analogue Devices, Inc., topology, these zero-drift amplifiers combine low cost with high accuracy and low noise. No external capacitor is required. In addition, it greatly reduces the digital switching noise found in most chopper-stabilized amplifier. 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 this to reduce input biasing complexity and maximize SNR.
