MAX9648:General-Purpose, Low-Voltage, Single Comparators in Tiny Packages

Pin-for-Pin Compatible Replacements for LMX331/LMX331H

The MAX9647/MAX9648 comparators are drop-in, pin-for-pin compatible replacements for the LMX331/LMX331H. The MAX9648 has the added benefit of internal hysteresis to provide noise immunity, preventing output oscillations even with slow moving input signals. Advantage of the ICs include low supply voltage, small package, and low cost. They also offer a wide supply voltage range, wide operating temperature range, competitive CMRR and PSRR, response time characteristics, input offset, low noise, output saturation voltage, input bias current and RF immunity. The ICs are available in both 5-pin SC70 and SOT23 packages.
