1. DESCRIPTION

The TLV3011 is a low-power, open-drain output comparator; the TLV3012AIDBVT 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 TLV3012AIDBVT are available in the tiny SOT23-6 package for 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.

4. APPLICATIONS INFORMATION

The TLV3012AIDBVT is a low-power, open-drain comparator with on-chip 1.242V series reference. The open-drain output allows multiple devices to be driven by a single pull-up resistor to accomplish an OR function, making the TLV3011 useful for logic applications. The TLV3012AIDBVT comparator with on-chip 1.242V series reference has a push-pull output stage optimal for reduced power budget applications and features no shoot-through current. A typical supply current of 2.8µA and tiny packaging combine with 1.8V supply requirements to make the TLV3011 and TLV3012 optimal for battery and portable designs.
