AOZ6232
0.25Ω Low-Voltage Dual-SPDT Analog Switch
General Description
Features
The AOZ6232 is a 0.25Ω low-voltage Dual Single Pole
Double Throw (SPDT) analog switch. The AOZ6232
operates from a single 1.65V to 3.3V supply. It features
an ultra-low On Resistance of 0.25Ω at a +2.7V supply
and 25°C. The AOZ6232 is designed for break-beforemake operation.

Typical 0.25Ω On Resistance (RON) for +2.7V supply

0.15Ω maximum RON flatness for +2.7V 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 3.0V 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. RON = 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.
