The MAX9321EUA is an IC component manufactured by Maxim Integrated. It is a precision programmable gain amplifier (PGA) specifically designed for various high-precision sensor applications. This device facilitates signal conditioning, amplification, and filtering to achieve accurate measurements in systems with demanding performance requirements.
The key features of the MAX9321EUA include a digitally programmable gain amplifier with a gain range from 0.5 to 128. Its high gain accuracy, typically 0.04% and maximum gain error of 0.2%, ensures precise amplification of the input signal. The PGA offers an input voltage range that extends from the negative power supply rail to within 300mV of the positive supply. This allows for the amplification of signals that are bipolar and span the entire supply range.
Moreover, this versatile component operates from a single power supply between 2.7V and 11V, making it suitable for a wide range of applications. It offers a low quiescent supply current of typically 180μA, minimizing power consumption. The MAX9321EUA also provides a rail-to-rail output swing, allowing it to drive signals all the way to the supply rails.
To enhance its versatility, this component can be programmed through its serial interface, allowing easy configuration of the gain and other settings using a microcontroller or digital potentiometer. This feature eliminates the need for external components, increasing simplicity and reducing circuit board area
