TPA3244 SLASEC6 – APRIL 2016 TPA3244 40-W Stereo, 100-W peak PurePath™ Ultra-HD Pad Down Class-D Amplifier 1 1 Features 1 • Differential Analog Inputs • Total Output Power at 10%THD+N – 40-W Stereo Continuous into 8 Ω in BTL Configuration at 30 V – 100-W Stereo Peak into 4 Ω in BTL Configuration at 30 V • Total Output Power at 1%THD+N – 35-W Stereo Continuous into 8 Ω in BTL Configuration at 30 V – 80-W Stereo Peak into 4 Ω in BTL Configuration at 30 V • Advanced Integrated Feedback Design with High- speed Gate Driver Error Correction (PurePath™ Ultra-HD) – Signal Bandwidth up to 100 kHz for High Frequency Content From HD Sources – Ultra Low 0.005% THD+N at 1 W into 4 Ω and <0.01% THD+N to Clipping – 60 dB PSRR (BTL, No Input Signal) – <55 µV (A-Weighted) Output Noise – >110 dB (A Weighted) SNR • Multiple Configurations Possible: – Stereo, Mono, 2.1 and 4xSE • Click and Pop Free Startup and Stop • 92% Efficient Class-D Operation (8 Ω) • Wide 12-V to 30-V Supply Voltage Operation • Self-Protection Design (Including Undervoltage, Overtemperature, Clipping, and Short Circuit Protection) With Error Reporting • EMI Compliant When Used With Recommended System Design 2 Applications • High End Soundbar • Mini Combo Systems • Blu-ray Disk™ / DVD Receivers • Active Speakers 3 Description The TPA3244 device is a high performance Class-D power amplifier that enables true premium sound quality with Class-D efficiency. It features an advanced integrated feedback design and proprietary high-speed gate driver error correction (PurePath™ Ultra-HD). This technology allows ultra low distortion across the audio band and superior audio quality. With a 30-V power supply the device can drive up to 2 x 100 W peak into 4- Ω load and 2 x 40 W continuous into 8- Ω load and features a 2-VRMS analog input interface that works seamlessly with high performance DACs such as TI's PCM5242. In addition to excellent audio performance, TPA3244 achieves both high power efficiency and very low power stage idle losses below 1 W. This is achieved through the use of 60 m Ω MOSFETs and an optimized gate driver scheme that achieves significantly lower idle losses than typical discrete implementations. Table 1.
