1 / 36 page PurePath TM HD Power Supply Ref. Design 110 VAC 240 VAC ® TAS5630 25 V–50 V ANALOG AUDIO INPUT 12 V PurePath TM HD TAS5616 (2.1 Configuration) TAS3308 Digital Audio Processor With Analog Interface DIGITAL AUDIO INPUT +3.3V REG. ♪ ♪ ♪ TAS5616 www.ti.com SLAS596B – JUNE 2009 – REVISED JANUARY 2010 160-W STEREO / 300-W MONO PurePath™ HD DIGITAL-INPUT POWER STAGE Check for Samples: TAS5616 1 FEATURES APPLICATIONS • Mini Combo System 23 • PurePath™ HD Enabled Integrated Feedback Provides: • AV Receivers • DVD Receivers – Signal Bandwidth up to 80 kHz for High-Frequency Content From HD Sources • Active Speakers – Ultralow 0.03% THD at 1 W into 8 Ω DESCRIPTION – Flat THD at All Frequencies for Natural Sound The TAS5616 is a high-performance PWM-input class-D amplifier with integrated closed-loop – 80-dB PSRR (BTL, No Input Signal) feedback technology (known as PurePath™ HD – >100-dB (A-weighted) SNR technology). It has the ability to drive up to 160-W – Click- and Pop-Free Startup (1) stereo into 8-Ω speakers from a single 50-V supply. – Minimal External Components Compared to Discrete Solutions PurePath™ HD technology enables traditional • Multiple Configurations Possible on the Same AB-amplifier performance (<0.03% THD) levels while providing the power efficiency of traditional class-D PCB With Stuffing Options: amplifiers. – Mono Parallel Bridge-Tied Load (PBTL) Ultralow 0.03% THD+N is flat across all frequencies, – Stereo Bridge-Tied Load (BTL) ensuring that the amplifier does not add uneven – 2.1 Single-Ended Stereo Pair and distortion characteristics, and helps maintain a natural Bridge-Tied Load Subwoofer sound. – Quad Single-Ended Outputs The efficiency of this class-D amplifier is greater than • Total Output Power at 10% THD+N 90%. Undervoltage protection, overtemperature, – 330 W in Mono PBTL Configuration clipping, short-circuit and overcurrent protection are all integrated, safeguarding the device and speakers – 160 W per Channel in Stereo BTL against fault conditions that could damage the Configuration system. PurePath HD™ – 80 W per Channel in Quad Single-Ended Configuration • High-Efficiency Power Stage (>90%) With 120-m Ω 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 (1) Achievable output power levels are dependent on the thermal configuration of the target application. A high performance thermal interface material between the package exposed thermal pad and the heat sink should be used to achieve high output power levels. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 PurePath HD is a trademark of Texas Instruments. 3 All other trademarks are the property of their respective owners.
