Overview
The TAS5630BPHDR is a high-performance analog-input class-D amplifier produced by Texas Instruments. It features integrated closed-loop feedback technology known as PurePath HD technology, which enables the device to drive up to 300 W of output power. The achievable output power levels are dependent on the thermal configuration of the target application, and a high-performance thermal interface material should be used between the exposed package heat slug and the heat sink to achieve high output power levels. This amplifier is designed to provide traditional AB-amplifier performance with the efficiency of class-D amplifiers, making it suitable for various audio applications.
