TAS2118 Evaluation Module
Description
The TAS2118EVM has been designed to demonstrate
the performance of TAS2118 in a mono configuration.
The EVM utilizes the AC-MB to provide a USB to
Audio interface to the EVM. Up to four devices
can share a common bus through I
interfaces. The TAS2118EVM also supports a dual-
mono configuration by combining two TAS2118EVMs.
