The ISL54211EVAL1Z evaluation board is designed to provide a quick and easy method for evaluating the ISL54211 USB audio switch IC.
The ISL54211 dual Single Pole/Double Throw (SPDT) switches combine low distortion audio and accurate USB 2.0 High-Speed data (480Mbps) signal switching in the same low voltage device. When operated with a 2.7V to 5.0V single supply, these analog switches allow audio signal swings below-ground, allowing the use of a common USB and audio headphone connector in personal media players and other portable battery-powered devices.
The ISL54211 TDFN IC is soldered onto the evaluation board. It is located in the center of the board and is designated as U1. The ISL54211 IC has three modes of operation—Audio mode, USB mode and Mute mode. And, the ISL54211EVAL1Z evaluation board contains standard audio and USB connectors to allow the user to easily interface with the IC to evaluate its functions, features and performance in these modes of operation.
