It features an advanced • Advanced Integrated Feedback Design with High- integrated feedback design and proprietary high- speed gate driver error correction (PurePath™ Ultra- speed Gate Driver Error Correction HD). This technology allows ultra low distortion (PurePath™ Ultra-HD) across the audio band and superior audio quality. – Signal Bandwidth up to 100 kHz for High With a 32V power supply the device can drive up to 2 Frequency Content From HD Sources x 130 W peak into 4- Ω load and 2 x 70 W continuous – Ultra Low 0.005% THD+N at 1 W into 4 Ω and into 8- Ω load and features a 2 VRMS analog input <0.01% THD+N to Clipping interface that works seamlessly with high performance DACs such as TI's PCM5242. In – 60 dB PSRR (BTL, No Input Signal) addition to excellent audio performance, TPA3250D2 – <60 µV (A-Weighted) Output Noise achieves both high power efficiency and very low – >110 dB (A Weighted) SNR power stage idle losses below 1 W. This is achieved through the use of 60 m Ω MOSFETs and an • Multiple Configurations Possible: optimized gate driver scheme that achieves – Stereo, Mono, 2.1 and 4xSE significantly lower idle losses than typical discrete • Click and Pop Free Startup and Stop implementations. • 92% Efficient Class-D Operation (8 Ω) Device Information(1) • Wide 12-V to 36-V Supply Voltage Operation PART NUMBER PACKAGE BODY SIZE (NOM) • Self-Protection Design (Including Undervoltage, TPA3250D2 HTSSOP (44) 6.10mm x 14.00mm Overtemperature, Clipping, and Short Circuit (1) For all available packages, see the orderable addendum at Protection) With Error Reporting the end of the datasheet.
