描述 Description

The TLV3011 is a low-power, open-drain output comparator;the TLV3012 is a push-pull output comparator. Both feature an uncommitted on-chip voltage reference. Both have 5μA (max) quiescent current, input common-mode range 200mV beyond the supply rails, and single-supply operation from 1.8V to 5.5V. The integrated 1.242V series voltage reference offers low 100ppm/°C (max) drift, is stable with up to 10nF capacitive load, and can provide up to 0.5mA (typ) of output current.

The TLV3011 and TLV3012 are available in the tiny SOT23-6 package for the most space-conservative designs. It is also available in the SC70 package for even greater board area savings. Both versions are specified for the temperature range of ?40°C to +125°C.
