The Texas Instruments TPA3100D2PHPR is an efficient Class-D audio power amplifier designed for driving bridged-tied stereo speakers. It delivers up to 20W per channel into an 8-ohm load from an 18V supply, or 10W per channel into an 8-ohm load from a 12V supply. The amplifier operates over a wide supply voltage range of 10V to 26V and can handle speaker loads as low as 4 ohms.
Featuring 92% efficiency, the TPA3100D2PHPR minimizes heat generation, often eliminating the need for external heat sinks during music playback. It accepts analog input and offers four selectable fixed gain settings. The device includes essential protection features such as thermal and short-circuit protection with auto-recovery. A clock output is provided for synchronization with multiple Class-D devices.
This amplifier is available in surface-mount packages, including a 48-pin VQFN (7mm x 7mm) and a 48-pin HTQFP (9mm x 9mm). Its design makes it suitable for applications such as televisions and other home audio systems requiring compact and efficient audio amplification.
