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 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.
