3 Description
The TLV7081 is a single-channel, nano-power
comparator that operates down to 1.7 V. The
comparator is available in an ultra-small, WCSP
package measuring 0.7 mm × 0.7 mm, making the
TLV7081 applicable for space-critical designs like
smartphones and other portable or battery-powered
applications.
The TLV7081 features a wide input-voltage range
that is independent of supply voltage. Having an input
range that is independent of supply voltage allows the
TLV7081 to be directly connected to sources that are
active even if the TLV7081 is not powered.
The TLV7081 has an open-drain output stage that
can be pulled beyond V+, making it appropriate for
level translators and bipolar to single-ended
converters.
