Operating over a low voltage range from 2.7V to 5.5V and at a typical supply current at 5V of only 40 µA for the LMV331 and 70 µA for the LMV393, the comparators are cost-effective drop-in replacements which help reduce overall system power consumption. Their extended operating temperature range, from -40ºC to +125ºC, also ensures compatibility with industrial system designs.
The LMV393 dual-channel comparator is provided in 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.
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 from Diode Incorporated are priced respectively at $0.55 and $0.72 each (1000).
