The TAS5631 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- to 8- 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.
●Unlike traditional class-D amplifiers, the distortion curve only increases once the output levels move into clipping.
●PurePath HD technology enables lower idle losses, making the device even more efficient.
● 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
● 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-m Output MOSFETs
● Two Thermally Enhanced Package Options:
● PHD (64-Pin QFP)
● DKD (44-Pin PSOP3)
● Self-Protection Design (Including Undervoltage, Overtemperature,
●Clipping, and Short-Circuit Protection) With Error Reporting
● EMI Compliant When Used With Recommended System Design
● APPLICATIONS
● Mini Combo System
● AV Receivers
● DVD Receivers
● Active Speakers
