The MAX74812 is a low noise, zero-drift operational amplifier and provides rail-to-rail input and output swing. The MAX74812 suits applications that cannot tolerate error sources by providing a 5μV offset voltage, a 0.015μV/°C offset voltage drift, and a typical noise of 99nV p-p (0.1Hz to 10Hz, AV = +100).
The MAX74812 provides a wide operating supply range of 2.2V to 5.5V, high gain, and excellent common-mode rejection ratio (CMRR) and power-supply rejection ratio (PSRR) specifications. These features make it ideal for applications that require precision amplification of lowlevel signals, such as position and pressure sensors, strain gauges, and medical instrumentation.
The MAX74812 operates over the extended industrial temperature range (−40°C to +125°C) and is available in 8-lead [MSOP] (RM-8) package.
