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 R_ON for its NC switch and
0.8Ω 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 and features break-before-make
switching action.
The LMS4684 is available in the 12-bump DSBGA
and the 10-lead WSON miniature packages. These
PCB real estate saving packages offer extreme
performance while saving money with small
footprints.
