The Texas Instruments TPA3126D2DADR is a highly efficient Class-D audio amplifier designed for home audio, speaker, TV, and soundbar applications. It delivers 50W of stereo output power into a 4Ω load at 21V with 10% THD+N, and can also be configured for 100W mono output.
This amplifier operates from a wide supply voltage range of 4.5V to 26V, making it versatile for various power requirements. Key features include ultra-low idle current of 15mA at 12V for longer battery-operating time, and a hybrid modulation scheme that dynamically reduces power loss. The low RDS(on) of 90mΩ contributes to over 90% efficiency.
Designed for ease of use, it supports stereo, mono BTL, and mono PBTL configurations. The device offers multiple switching frequencies from 300kHz to 1.2MHz for AM avoidance and master/slave synchronization. Selectable gains of 20dB, 26dB, 32dB, and 36dB are available, along with programmable power limit functionality. Integrated protections include overvoltage, undervoltage, overtemperature, DC-detect, and short circuit reporting.
The TPA3126D2DADR is housed in a thermally enhanced 32-pin HTSSOP PowerPAD package, suitable for surface mount applications. Its performance is an upgrade from the TPA3116D2, offering 70% less idle current and pin-to-pin compatibility.
