LMS4684 0.5 Low-Voltage, Dual SPDT Analog Switch
June 2004
LMS4684 0.5 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 0.5 RON for its NC switch and 0.8 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.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is intended to be functional, but specific performance is not guaranteed. Note 2: Human body model: 1.5k in series with 100pF. Machine model, 0 in series with 200pF. Note 3: The maximum power dissipation is a function of TJ(max) JA and TA. Note 4: Guaranteed by design. Note 5: RON is equal to the difference between NC1/NC2 RON or NO1/NO2 RON at a specified voltage. Note 6: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the specified analog signal ranges.
