Product Description
 
The UM3699A are dual independent ultra low RON DPDT analog switches. 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.
