AOZ6234QI#A

AOZ6234 0.25Ω Low-Voltage Dual-SPDT Analog Switch General Description Features The AOZ6234 is a 0.25Ω low-voltage Dual Single Pole Double Throw (SPDT) analog switch. The AOZ6234 operates from a single 2.3V to 4.3V supply. It features an ultra-low On Resistance of 0.25Ω at a +4.3V supply and 25°C. The AOZ6234 is designed for break-before-make operation. The AOZ6234 features very low quiescent current, even when the control voltage is lower than the VCC supply. This feature services the mobile handset applications very well, allowing for the direct interface with baseband processor general-purpose I/Os. ● Typical 0.25Ω On Resistance (RON) for +4.3V supply ● Features less than 30µA ICCT current when S Input is lower than VCC ● 0.15Ω maximum RON flatness for +4.3V supply ● 1.6mm x 2.1mm QFN package ● Broad VCC operating range ● Low THD (0.02% typical for 32Ω load) ● High current handling capability (350mA continuous current under 3.3V supply) Applications ● Cell phone ● PDA ● Portable media player Typical Application Pin Configuration AOZ6234 Earpiece 1B0 1A 1B1 S1 1S Integrated Base Band Processor 2B0 2A 2B1 S2 2S Internal Speaker Rev. 2.0 February 2010 www.aosmd.com Page 1 of 11 AOZ6234 Ordering Information Part Number Ambient Temperature Range Package Environmental AOZ6234QI -40°C to +85°C QFN-10 RoHS Compliant Green Product AOS Green Products use reduced levels of Halogens, and are also RoHS compliant.
