AOSMD AOZ6234QI 0.25ohm low-voltage dual-spdt analog switch Datasheet

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

Notes:
4. On resistance is determined by the voltage drop between A and B pins at the indicated current through the switch.
5. ΔRON = RONmax – RONmin measured at identical VCC , temperature, and voltage.
6. Flatness is defined as the difference between the maximum and minimum value of RON over the specified range of conditions.
