Frequently Asked Questions
What is the operating voltage range for these comparators?
The devices operate from low-voltage (2.7 V to 5.5 V) or standard ranges of 5 V to 30 V.
Which device version is best for portable, low-power applications?
LMV331, LMV339, and LMV393 are cost-effective solutions prioritizing low voltage, low power, and small size.
What specification determines the output flexibility of the lMV series comparison?
The open-collector output provides maximum flexibility for the comparators.
How is package thermal impedance rated?
It depends on the specific package; for example, an 8-pin D package has a thermal impedance of 97°C/W.
