TI TPA3255DDVR STOCK

The TPA3255DDVR is a high‑performance Class‑D power amplifier that delivers 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), enabling ultra‑low distortion across the audio band and superior audio quality . Operating in AD‑mode, the device drives up to 2 × 315 W into 4‑Ω loads (10% THD+N) in BTL configuration, 2 × 150 W unclipped into 8‑Ω loads, and up to 600 W mono into 2‑Ω loads in PBTL configuration -4-6. The 2‑VRMS analog input interface works seamlessly with high‑performance DACs such as the TI PCM5242 -1-3. With 90% efficiency at 4 Ω and idle losses below 2.5 W (using 85‑mΩ MOSFETs and an optimized gate driver scheme), the TPA3255DDVR achieves high power efficiency while maintaining low power consumption. The device supports multiple output configurations (stereo, mono, 2.1, and 4×SE) and includes comprehensive protection features: undervoltage, overtemper

Description:

TPA3255 is a high performance class-D poweramplifier that enables true premium sound qualitywith class-D efficiency. It features an advancedintegrated feedback design and proprietary highspeed gate driver error correction (PurePath™ UltraHD). This technology allows ultra low distortionacross the audio band and superior audio quality.The device is operated in AD-mode, and can drive upto 2 x 315 W into 4-Ω load at 10% THD and 2 x 150W unclipped into 8-Ω load and features a 2 VRMSanalog input interface that works seamlessly with highperformance DACs such as TI's PCM5242. Inaddition to excellent audio performance, TPA3255achieves both high power efficiency and very lowpower stage idle losses below 2.5W. This is achievedthrough the use of 85 mΩ MOSFETs and anoptimized gate driver scheme that achievessignificantly lower idle losses than typical discreteimplementations.
