from a 1.8V to 5.5V supply. The LMS4684 features a 0.5鈩?/div>
R

for its NC switch and 0.8鈩?R
ON
for its NO switch at a
2.7V supply. The digital logic inputs are 1.8V logic-
compatible with a 2.7V to 3.3V supply.
The LMS4684 is available in the 12 bump micro SMD and
the 10 lead LLP miniature packages. These PCB real estate
saving packages offer extreme performance while saving
money with small footprints.
