Single/dual channel comparators boost performance

Diodes has introduced enhanced versions of its LMV331 and LMV393 single and dual channel comparators, designed for use in battery powered portable devices such as mobile phones and notebook PCs.

These general purpose devices run at a lower voltage, draw less current and are said to be available in smaller package options than most industry standard alternatives.

Operating over a low voltage range from 2.7 to 5.5V and at a typical supply current at 5V of only 40µA for the LMV331 and 70µA for the LMV393, the comparators are offered as cost effective drop-in replacements which help reduce overall system power consumption.

Their extended operating temperature range, from -40 to 125ºC, also ensures compatibility with industrial system designs.

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

To maximise flexibility, the comparators' input common-mode voltage range includes ground and extends from -0.1 to 2V. Output type is open-collector.
