Single- and Dual-Channel Comparators Boost Performance

Published: May 13,2014

Diodes Incorporated introduced enhanced versions of the popular LMV331 and LMV393 single- and dual-channel comparators for use in battery-powered portable devices such as mobile phones and notebook PCs. These generalpurpose devices run at a lower voltage, draw less current and offer smaller package options than most industry-standard alternatives.

Operating at a low voltage range of 2.7V to 5.5V, the comparators feature a

typical supply current at 5V of only 40μA for the LMV331 and 70μA for the

LMV393, and are cost-effective drop-in replacements that help reduce overall

system power consumption. The devices feature an extended operating

temperature range (-40oC to +125oC), making them compatible with industrial system designs.

The LMV393 dual-channel comparator is provided in the industry-standard SO-8 and MSOP-8 packages, while the single-channel LMV331 is offered in the spacesaving 5-pin SOT353 and SOT25 formats, helping to shrink circuit size in portable products.

To maximize flexibility, the comparators’ input common-mode voltage range

includes ground and extends from -0.1V to +2V while featuring an open collector output.
