AOSMD AOZ6238

AOZ6238
0.35  Low-Voltage Dual SPDT Analog Switch
General Description
Features
The AOZ6238 is a 0.35 Ω low-voltage Dual Single Pole
Double Throw (SPDT) analog switch. The AOZ6238
operates from a single 1.65 V to 4.3 V supply. It features
an ultra-low On Resistance of 0.35 Ω at a +3.0 V supply
and 25 °C. The AOZ6238 is designed for break-beforemake operation.
 Typical 0.35
 0.15
Ω On Resistance (RON) for +3.0 V supply
Ω maximum RON flatness for +3.0 V supply
 Package Options:
– TQFN-10: 1.8 mm x 1.4 mm x 0.55 mm package
– QFN-10: 1.8 mm x 1.4 mm x 0.75 mm package
 Broad VCC operating range: 1.65 V to 4.3 V
 High current handling capability (350 mA continuous
current under 3.3 V supply)
 Internal 225
Ω resistor for “pop” free switching
Applications
 Cell phone
 PDA
 Portable media player
