Comparators for battery-powered portable devices
Suited for use in battery-powered portable devices such as mobile phones and notebook PCs, Diodes has introduced enhanced versions of the popular LMV331 and LMV393 single- and dual-channel comparators. They operate over a low voltage range of 2.7-5.5V and at a typical supply current at 5V of only 40µA for the LMV331 and 70µA for the LMV393.
According to the manufacturer, these general-purpose devices run at a lower voltage, draw less current and offer smaller package options than most industry-standard alternatives. The comparators are 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 the industry-standard SO-8 and MSOP-8 packages, while the single-channel LMV331 is offered in the space-saving 5-pin SOT353 and SOT25 formats, helping to shrink circuit size in portable products.
In order to maximise flexibility, the comparators’ input common-mode voltage range includes ground and extends from -0.1V to +2V. Output type is open-collector.
The LMV331 single-channel and LMV393 dual-channel comparators are respectively priced at $55 (USD) and $72 (USD) each in 1,000 unit quantities. They are supplied in 2,500 and 3,000 piece reels.
