DESCRIPTION
The UTC LMV3012 is a push-pull output comparator and can
provide an independent on-chip voltage reference. The UTC
LMV3012 has 5µA (max) quiescent current, input common-mode
range 200mV beyond the supply rails. Single-supply operation
can range from 1.8V to 5.5V. The integrated 1.242V series
voltage reference with low 100ppm/°C (max) drift, is stable with
up to 10nF capacitive load, and the output current can be up to
0.5mA (Typ).
The UTC LMV3012 is also available in the tiny SC59-6
package for space-conservative designs. The device is specified
for the temperature range of -40°C~+125°C.

Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.5V
beyond the supply rails should be current limited to 10mA or less.
