Analog Devices Inc. MAX74811 Rail-to-Rail Dual Operational Amplifiers
Analog Devices MAX74811 Rail-to-Rail Dual Operational Amplifiers are wide bandwidth auto-zero amplifiers featuring rail-to-rail input and output swing, low noise, and 5V single supply operation. These zero-drift amplifiers combine low cost with high accuracy and low noise. In addition, the MAX74811 greatly reduces the digital switching noise found in most chopper-stabilized amplifiers. The 8-lead MSOP plastic packaged MAX74811 is specified for an extended industrial temperature range of -40°C to +125°C.
With an offset voltage of only 1µV (typical), drift of 5nV/°C (typical), and noise of only 0.5µV p-p (0.1Hz to 10Hz) (typical), the Analog Devices MAX74811 is suited for applications where error sources cannot be tolerated. Position and pressure sensors, medical equipment, and strain gauge amplifiers benefit greatly from nearly zero drift over the specified operating temperature range. Many systems can take advantage of the rail-to-rail input and output swings provided by the MAX74811 to reduce input biasing complexity and maximize signal-to-noise ratio (SNR).
