The MAX74811 is a wide bandwidth auto-zero amplifier featuring rail-to-rail input and output swing and low noise. 5V single supply operation is specified.

The MAX74811 zero-drift amplifier combines low cost with high accuracy and low noise. In addition, the MAX74811 greatly reduces the digital switching noise found in most chopper-stabilized amplifiers.

With an offset voltage of only 1μV (typ), drift of 5nV/°C (typ), and noise of only 0.5μV p-p (0.1Hz to 10Hz) (typ), the 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 their 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).

The MAX74811 is specified for the extended industrial temperature range (−40°C to +125°C). The MAX74811 is available in the standard 8-lead MSOP plastic package.
