Linear-Comparators provide electronics engineers with an automated differential comparison of the two similar signals, turning the comparison into a numerical result. MAX9691ESA+T is a Linear-Comparator application that provides reliable operation and numerous features, giving engineers a vast array of design options across numerous applications.

The MAX9691ESA+T is an operational amplifier and comparator that combines programmable hysteresis and adjustable shutdown functions with high-speed operation and low power consumption. It includes two fixed-gain gain stages and one adjustable-gain stage. The adjustable stage is used to set up a desired comparator output voltage. It also has a quiescent current of 1.1µA, allowing engineers to monitor battery-powered applications for longer periods of time.

The MAX9691ESA+T uses a self-calibrated voltage reference for excellent accuracy and low supply current. This low current operation contributes to extended battery life in portable applications. It also features an adjustable gain stage via a simple external resistor network providing programmable hysteresis to minimize unwanted auto transitions. This allows the user to precisely adjust the output response time to meet the requirements of specific application needs.

The Linear-Comparator also includes a selectable shutdown mode. This allows the comparator to be powered down through a device pin following the input termination in order to save power. This shutdown mode binds together the shutdown circuit and comparator power into one supply line, resulting in a compact, low-power solution for compact designs.

The MAX9691ESA+T is ideally suited for applications in battery-powered systems, voltage and current comparators, level-shifts, and temperature and other sensing applications. It can also be used in vehicle applications, such as direct Injection, EGR, ABS, and engine monitoring systems.

The working principle of the MAX9691ESA+T is fairly straightforward. It consists of two input pins, one positive and one negative, and three output pins. The positive input is the reference voltage and is compared to the voltage on the negative input pin. The output pins are then used to output the comparison result.

The MAX9691ESA+T is a highly reliable and cost effective Linear-Comparator that provides ease of use, accurate results, and extended battery life in numerous applications. It’s adjustable gain stage provides programmable hysteresis and adjustable shutdown functions, allowing engineers of all disciplines to accurately and quickly develop products for a variety of applications.
