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.
