It features an advanced speed Gate Driver Error Correction integrated feedback design and proprietary high- speed gate driver error correction (PurePath™ Ultra- (PurePath™ Ultra-HD) HD). This technology allows ultra low distortion – Signal Bandwidth up to 100 kHz for High across the audio band and superior audio quality. Frequency Content From HD Sources The device can drive up to 2 x 175 W into 4- Ω load – Ultra Low 0.005% THD+N at 1 W into 4 Ω and and 2 x 220 W into 3- Ω load and features a 2 VRMS <0.01% THD+N to Clipping analog input 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, TPA3251D2 – <60 µV (A-Weighted) Output Noise achieves both high power efficiency and very low – >111 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. • 90% Efficient Class-D Operation (4 Ω) Device Information(1) • Wide 12-V to 36-V Supply Voltage Operation PART NUMBER PACKAGE BODY SIZE (NOM) • Self-Protection Design (Including Undervoltage, TPA3251D2 HTSSOP (44) 6.10mm x 14.00mm Overtemperature, Clipping, and Short Circuit Protection) With Error Reporting (1) For all available packages, see the orderable addendum at the end of the datasheet. • EMI Compliant When Used With Recommended System Design Simplified Schematic Total Harmonic Distortion 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
