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.
