The MAX934EPE+ from Maxim Integrated Products is an ultra low power, low cost quad comparator with 2% reference in 16 pin DIP package. It includes an internal 1.182V ±2% voltage reference and TTL/CMOS outputs that sink and source current. Ideal for 3V or 5V single supply applications, the MAX934 operate from a single +2.5V to +11V supply (or a ±1.25V to ±5V dual supply) and each comparator's input voltage range extends from the negative supply rail to within 1.3V of the positive supply. This low voltage micropower comparator continuously sources up to 40mA current and the unique output stage eliminates crowbar glitches during output transitions. This makes this device immune to parasitic feedback (which can cause instability) and provides excellent performance even when circuit board layout is not optimal. It is used in battery powered systems, threshold detectors, window comparators, oscillator circuits and alarm circuits.
