TPA3116D2DADR TI Audio Amplifiers

The TPA3116D2DADR is a highly efficient, filter‑free stereo (2 × 50 W) Class‑D audio amplifier from Texas Instruments. For selection, verify the power supply (PVCC) from 4.5 V to 26 V, load impedance (e.g., 4 Ω for 50 W or 8 Ω for 30 W), and PWM frequency (400 kHz to 1.2 MHz) to avoid AM interference. This device supports both differential and single‑ended inputs as well as mono parallel BTL (PBTL) mode (100 W into 2 Ω) for higher power. It features integrated protections (overvoltage, undervoltage, short circuit, thermal, DC detection) and offers >90% efficiency, which significantly reduces heat sink size. The operating ambient temperature range is –40°C to 85°C (junction: –40°C to 125°C). Ideal applications include mini/micro component speakers, soundbars, docking stations, aftermarket automotive audio, CRT TVs, and other consumer audio systems.
