Product Description

DESCRIPTION
The TAS5631B is a high-performance PWM input class-D amplifier with integrated closed-loop feedback technology (known as PurePath HD technology) with the ability to drive up to 300 W (1) stereo into 4-Ω to 8-Ω speakers from a single 50-V supply.
PurePath HD technology enables traditional AB-amplifier performance (<0.03% THD) levels while providing the power efficiency of traditional class-D amplifiers.
FEATURES
• PurePath™ HD Enabled Integrated Feedback Provides:
– Signal Bandwidth up to 80 kHz for
High-Frequency Content From HD Sources
– Ultralow 0.03% THD at 1 W Into 4 Ω
– Flat THD at All Frequencies for Natural Sound
– 80-dB PSRR (BTL, No Input Signal)
– >100-dB (A-weighted) SNR
– Click- and Pop-Free Start-Up
• Multiple Configurations Possible on the Same
PCB With Stuffing Options:
– Mono Parallel Bridge-Tied Load (PBTL)
– Stereo Bridge-Tied Load (BTL)
– 2.1 Single-Ended Stereo Pair and
Bridge-Tied Load Subwoofer
– Quad Single-Ended Outputs
• Total Output Power at 10% THD+N
– 600 W in Mono PBTL Configuration
– 300 W per Channel in Stereo BTL Configuration
– 145 W per Channel in Quad Single-Ended Configuration
• High-Efficiency Power Stage (>88%) With 60-mΩ Output MOSFETs
• Two Thermally Enhanced Package Options:
– PHD (64-Pin QFP)
– DKD (44-Pin PSOP3)
