UM3699A
Dual DPDT Ultra-Low R_ON Analog Switch
UM3699A QFN16 3.0×3.0
General Description
The UM3699A are dual independent ultra low R_ON DPDT analog switchs. These devices are
designed for low operating voltage, high current switching of speaker output for cell phone
applications. They can switch a balanced stereo output and can handle a balanced
microphone/speaker/ring−tone generator in a monophone mode. The UM3699A have no internal
shunt resistors, which make it compatible for switching data lines that keep a specific voltage
when the NO or NC terminals are not connected, avoiding power loss on the shunt resistors. The
devices also have a break-before-make feature that further reduces popping.
