3 Description

The TLV3011 is a low-power, open-drain output

comparator; the TLV3012 is a push-pull output

comparator. Both devices feature an uncommitted onchip

voltage reference and have a 5 μA (maximum)

quiescent current, an input common-mode range

200 mV beyond the supply rails, and single-supply

operation from 1.8 V to 5.5 V. The integrated 1.242

V series voltage reference offers low 100 ppm/°C

(maximum) drift, is stable with up to 10 nF capacitive

load, and can provide up to 0.5 mA (typical) of output

current.

The TLV3011B and TLV3012B B versions add

power-on-reset (POR), fail-safe inputs, built-in

hysteresis, a lower minimum supply voltage of 1.65

V and a 3.1 μA maximum quiescent current.

The family is available in both the tiny SOT23-6

package for space-conservative designs, and in the

SC-70 package for even greater board area savings.

All versions are specified for the temperature range of

–40°C to +125°C.
