The 3PEAK INCORPORATED LMV331-393 are themost cost-effective solutions for applications wherelow-voltage operation, low power, space saving, andprice are the primary specifications in circuit designfor portable consumer products. The LMV331TP isthe single-comparator, the LMV393TP is the dual,and both are open-drain output comparators formaximum flexibility.The chips incorporate 3PEAK’s proprietary andpatented design techniques to achieve the ultimatecombination of high-speed (120ns high-to-lowpropagation delay) and low power consuming (40μAquiescent current per comparator). Thesecomparators are optimized for low power 1.8V,single-supply applications with greater than rail-torail input operation, and also operate with ±0.9V to±2.75V dual supplies. The input common- modevoltage range extends 200mV below ground and200mV above supply, allowing both ground andsupply sensing. The internal input hysteresiseliminates output switching due to internal inputnoise voltage, reducing current draw.The LMV331 single comparator is available in tinySC70 package for space-conservative designs. Allchips are specified for the temperature range of –40°C to +85°C.
