Description

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.
