LMS4684

LMS4684 0.5Ω Low-Voltage, Dual SPDT Analog Switch June 2004 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 logiccompatible 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.
