TAS2574 Evaluation Module
Description
The TAS2574EVM has been designed to demonstrate
the performance of TAS2574 in a dual-mono
configuration. This tool utilizes the AC-MB
motherboard to provide an interface and supply
voltages to the EVM daughter card. Up to four devices
can share a common bus through I
interfaces; two EVMs can be mounted one on top of
each other, as shown in
