TAS2560EVM: 5.6-W Class-D Mono Audio Amplifier with IV Sense

Summary

The TAS2560 is an amplifier with an integrated 8.5V boost converter supporting Class-D, Class-G, and Class-H. The device supports up to 5.7W output while using a 4 Ohm driver and includes on-chip voltage and current sensing. Users can utilize this sensing to implement an advanced algorithm to provide real-time speaker protection against overheating and excessive excursion.
