General Description

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 RON of 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.
