产品概述

The 3PEAK INCORPORATED LMV331-393 are the most cost-effective solutions for applications where low-voltage operation, low power, space saving, and price are the primary specifications in circuit design for portable consumer products. The LMV331TP is the single-comparator, the LMV393TP is the dual, and both are open-drain output comparators for maximum flexibility. 


The chips incorporate 3PEAK’s proprietary and patented design techniques to achieve the ultimate combination of high-speed (120ns high-to-low propagation delay) and low power consuming (40μA quiescent current per comparator). These comparators are optimized for low power 1.8V, single-supply applications with greater than rail-to-rail input operation, and also operate with ±0.9V to ±2.75V dual supplies. 


The input common- mode voltage range extends 200mV below ground and 200mV above supply, allowing both ground and supply sensing. The internal input hysteresis eliminates output switching due to internal input noise voltage, reducing current draw. The LMV331 single comparator is available in tiny SC70 package for space-conservative designs. All chips are specified for the temperature range of –40°C to +85°C.
