LMV7219
7 nsec, 2.7V to 5V Comparator with Rail-to-Rail Output
General Description
The LMV7219 is a low-power, high-speed comparator with
internal hysteresis. The LMV7219 operating voltage ranges
from 2.7V to 5V with push/pull rail-to-rail output. This device
achieves a 7ns propagation delay while consuming only
1.1mA of supply current at 5V.
The LMV7219 inputs have a common mode voltage range
that extends 200mV below ground, allowing ground sensing.
The internal hysteresis ensures clean output transitions even
with slow-moving inputs signals.
The LMV7219 is available in the SC70-5 and SOT23-5
packages, which are ideal for systems where small size and
low power are critical.
