MAX972ESA is a single channel ultra-low-power comparator (LPC) with an output terminal for tiny logistics or data acquisition applications. The device is suitable for applications requiring high accuracy, low offset, and fast response. Its low-voltage operation ensures minimal power consumption and improved reliability over other comparators. The device contains an internal hysteresis feature (Hyst) that reduces extraneous noise and enables operation in a circuit with a wide range of input voltages.

The MAX972ESA is part of the Linear-Comparators (LPC) family of products. The LPC family includes devices that compare one digital signal to another in order to determine its logic state (e.g. high/low logic states). These comparators can be used in a wide range of applications such as signal control, fault detection, overvoltage protection, level shifting, signal synchronization and timing control.

The MAX972ESA operates in two modes: Normal Operation mode and Output-Level Adjustment mode. In Normal Operation mode, the chip compares two input voltages and if one of them is higher than the other, the output signal goes HIGH. In Output-Level Adjustment mode, the output-level of the signal can be adjusted via a voltage applied to the threshold pin. The hysteresis level can also be adjusted via a special configuration pin.

The device features an input voltage range from 2.4V to 5.5V and an output voltage range from 0.4V to 4.6V, making it ideal for applications demanding wide input and output voltage ranges. The device also features fast slew rate and a wide voltage window of ±2.0V to allow for precise output control, as well as low temperature coefficient and low supply noise immunity. The MAX972ESA is available in a small 8-pin SSOP package and is extremely power efficient, consuming only 3uA of current.

The MAX972ESA is an ideal solution for a wide range of applications such as sensor interface, wireless telemetry, motion detection, event counting and tracking. It is also well suited for applications with tight power requirements where low power consumption, small size and wide input/output voltage range are needed.

The device is designed to operate over a wide temperature range from -40°C to +85°C and is built on the proprietary process technology to provide excellent performance characteristics, reliability and robustness. With advanced engineering and reliable construction, the MAX972ESA is a robust and reliable solution for various applications demanding extreme accuracy and low power consumption.
