LMS4684LD/NOPB

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 R₀ₙ 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. The LMS4684 is a low voltage dual, extremely low On-Resistance analog switch that can operate over a supply voltage range of 1.8V to 5.5V. The LMS4684 has been fully characterized to operate in applications with 3V nominal supply voltage and features very low on resistance and fast Turn-Off and Turn-On times with break-before-make switching. The switch operates asymmetrically; one terminal is normally closed (NC) and the other terminal normally open (NO). Both NC and NO terminals are connected to a common terminal (COM). This configuration is ideal for applications with asymmetric loads such as speaker handsets and internal speakers.
