High Speed, Low Voltage, Dual, DPDT Analog Switch
UM3670 QFN16 3.0×3.0
UM3670A QFN16 2.6×1.8
General Description
The UM3670/3670A is a high speed, dual, dual-pole/double-throw (DPDT) analog switch
operates from a single +1.8V to +5.5V power supply. The UM3670/3670A features dual 5Ω R_ON
(TYP) DPDT switches with 300MHz bandwidth and low crosstalk. The switch offers a
high-performance, low-cost solution to switch between video sources. The switch is available in
Pb-free QFN16 package.
