LMS4684
0.5Ω Low-Voltage, Dual SPDT Analog Switch
General Description
The LMS4684 is a low on-resistance, low voltage dual SPDT
(Single-Pole/Double-Throw) analog switch that operates
from a 1.8V to 5.5V supply. The LMS4684 features a 0.5Ω
RON for its NC switch and 0.8Ω RON 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.
