MAXIM INTEGRATED / ANALOG DEVICES MAX981CUA Ultra-Low Power Comparator

The MAX981CUA+ from Maxim Integrated Products is an ultra-low power, single low-voltage comparator housed in an 8-pin µMAX package. This micropower device operates from a single or dual supply, drawing less than 4µA of current over a wide temperature range. It features an internal ±2% voltage reference, programmable hysteresis, and open-drain outputs allowing wire-OR configurations. The comparator supports input voltages from the negative supply rail up to within 1.3V of the positive supply, making it suitable for 3V or 5V single supply applications. It has an output voltage range of up to 11V with a separate ground pin for the output transistor, ideal for level translation and bipolar-to-single-ended conversion. The MAX981CUA+ is suitable for use in battery-powered systems, threshold detection, level translation, window comparison, and oscillator circuits.
