The MAX9311ECJ is an integrated circuit (IC) component designed to provide precision current sensing with a wide input voltage range. It offers various key features that make it a versatile option for current monitoring applications.
One of the main features of the MAX9311ECJ is its ability to measure currents ranging from -1A to +20A. This wide measurement range makes it suitable for a broad range of applications, such as power management, battery monitoring, and motor control systems.
The IC component operates on a single power supply voltage ranging from 2.7V to 18V, making it compatible with a wide range of power sources. It also includes an integrated voltage reference, eliminating the need for an external reference source.
The MAX9311ECJ offers high precision current measurement with a typical accuracy of ±0.5% full scale. This level of accuracy ensures reliable and precise current monitoring in various demanding applications.
To achieve accurate current measurements, the IC incorporates a low-offset, high-bandwidth amplifier. This amplifier minimizes any errors introduced by voltage drops across the sense resistor, resulting in accurate and faithful current readings.
The IC features a shutdown mode that reduces power consumption when not in use, making it suitable for battery-powered applications where energy efficiency is crucial.
Another key feature is its ability to provide both a current output proportional to the sensed current and a voltage output that represents the sensed current. This flexibility allows engineers to choose the output type that best suits their system requirements
