AD8630WARZ-R7

AD8630WARZ-R7 is a zero-drift, single-supply, rail-to-rail input/output operational amplifier. It provides benefits previously found only in expensive auto-zeroing or chopper-stabilized amplifiers. Using Analog Devices, Inc., topology, this zero-drift amplifier combines low cost with high accuracy and low noise. No external capacitor is required. In addition, this device greatly reduces 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 0.5µV p-p (0.1Hz to 10Hz), this device is suited for applications where error sources cannot be tolerated. It is used in applications such as automotive sensors, pressure and position sensors, strain gauge amplifiers, medical instrumentation, thermocouple amplifiers, precision current sensing, and photodiode amplifiers.
