The Texas Instruments TPA3116 is an efficient Class-D audio amplifier IC capable of delivering 50W of stereo output power into a 4-ohm load at 21V. It supports a wide analog supply voltage range from 4.5V to 26V, making it versatile for various audio systems.
This amplifier features advanced modulation schemes and multiple switching frequencies, including AM avoidance, operating up to 1.2 MHz. Its feedback power-stage architecture contributes to high power efficiency, exceeding 90%, which helps reduce heatsink size and power loss. The TPA3116 is housed in a thermally enhanced 32-pin HTSSOP package.
Key electrical characteristics include a low RDS(on) of 0.12 ohms and THD+N of 0.1% at 1 kHz. It supports stereo and mono modes with differential and single-ended inputs. Integrated self-protection circuits enhance reliability. The wide voltage range and high efficiency make it suitable for home audio, TV, and soundbar applications.
The TPA3116 delivers 2x50W into 4Ω BTL loads at 21V, 2x30W into 8Ω BTL at 24V, and 2x15W into 8Ω BTL at 15V.
The power stage and analog supply voltage range is 4.5V to 26V.
The operating ambient temperature range is -40°C to 85°C.
The TPA3116 is housed in a HTSSOP (DAD) package measuring 11mm x 8.1mm with an area of 89.1mm².
THD+N is 0.1% at 1kHz.
The amplifier achieves >90% power efficiency.
The minimum load impedance is 4Ω.
