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.
● Typical 0.25Ω On Resistance (R ) for +4.3V supply
ON
● Features less than 30µA I
current when S Input is
CCT
lower than V
CC
● 0.15Ω maximum R
flatness for +4.3V supply
ON
● 1.6mm x 2.1mm QFN package
● Broad V operating range
The AOZ6234 features very low quiescent current, even
CC
when the control voltage is lower than the V supply.
CC
● Low THD (0.02% typical for 32Ω load)
This feature services the mobile handset applications
very well, allowing for the direct interface with baseband
processor general-purpose I/Os.
● High current handling capability (350mA continuous
current under 3.3V supply)
Applications
● Cell phone
● PDA
● Portable media player
