Description
General part information
TS3A227E Series
The TS3A227E is an autonomous audio accessory detection and configuration switch that detects 3-pole or 4-pole audio accessories and configures internal switches to route the signals accordingly.
The internal ground FETS of the TS3A227E have an ultra-low RONof 60 mΩ to minimize crosstalk impact. The ground FETs are also designed to pass FM signals, making it possible to use the ground line of the accessory as an FM antenna in mobile audio applications.
Internal isolation switches allow the TS3A227E to remove the click/pop noise that can be generated during and insertion or removal of an audio accessory. In addition depletion FETs prevent a floating ground while the device is unpowered, removing the humming noise present when leaving accessories plugged into an unpowered system.
