AOSMD AOZ6185

AOZ6185
High-Speed USB and Audio DPDT Switch
General Description
Features
The AOZ6185 is a low-voltage high-speed Double-Pole,
Double-Throw (DPDT) switch for switching between two
sources. The device features very low on capacitance
(5 pF typ.) and is designed to operate from a single
1.65 V to 4.5 V supply. The AOZ6185 features an
ultra-low on resistance (5 Ω typ.) and on resistance
flatness (0.5 Ω typ.), making this device ideal for
applications where high speed data and audio switching
is needed. The device also features fast switching and
guaranteed Break-Before-Make (BBM) switching,
assuring the switches never short the driver.
z Low On Resistance (RON) for 4.5 V supply (5 Ω)
z Low On Capacitance (CON) for 4.5 V supply (5 pF)
z Low On Resistance flatness for 4.5 V supply (0.5 Ω)
z Over-voltage tolerance (OVT) on all data ports up to
5.5 V
z QFN-10: 1.8 mm x 1.4 mm x 0.55 mm
z Broad 1.65 V to 4.50 V VCC operating range
z Wide –3 dB bandwidth: 990 MHz typ.
Applications
z Cell phone
z PDA
z Portable media player
