175-W Stereo into 3
Ω in BTL Configuration
TPA3251D2 is a high performance class-D power
285-W Mono into 2
Ω in PBTL Configuration
amplifier that enables true premium sound quality
Advanced Integrated Feedback Design with High-
with class-D efficiency. 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
