1 / 64 page  1 FEATURES DESCRIPTION TAS5716 www.ti.com............................................................................................................................................................................................... SLOS569 – JANUARY 2009 20-W Stereo Digital-Audio Power Amplifier With EQ and DRC – Loudness Compensation for Subwoofer 23 • Audio Input/Output – Automatic Sample-Rate Detection and Coefficient Banking – 20 W Into an 8- Ω Load From an 18-V Supply – 3D Support – Two Serial Audio Inputs (Four Audio Channels) – Pseudo-Bass Support – Supports Multiple Output Configurations: • General Features – 2-Ch Bridged Outputs (20 W × 2) – Serial Control Interface Operational Without MCLK – 4-Ch Single-Ended Outputs (10 W × 4) – Factory-Trimmed Internal Oscillator Avoids – 2-Ch Single-Ended + 1-Ch Bridged (2.1) the Need for External Crystal (10 W × 2 + 20 W) – Surface Mount, 64-Terminal, 10-mm × • Closed-Loop Power-Stage Architecture 10-mm HTQFP Package – Improved PSRR Reduces Power Supply – Thermal and Short-Circuit Protection Performance Requirements – Higher Damping Factor Provides for Tighter, More Accurate Sound With Improved Bass Response The TAS5716 is a 20-W, efficient, digital-audio power amplifier for driving stereo bridged-tied speakers. Two – Constant Output Power Over Variation in serial data inputs allow processing of up to four Supply discrete audio channels and seamless integration to • Wide PVCC Range From (10 V to 26 V) most digital audio processors and MPEG decoders, – No Separate Supply Required for Gate accepting a wide range of input data and clock rates. A fully programmable data path allows these Drive channels to be routed to the internal speaker drivers • Supports 32-kHz–192-kHz Sample Rates or output via the subwoofer or headphone PWM (LJ/RJ/I2S) outputs. • Headphone PWM Outputs The TAS5716 is a slave-only device receiving all • Subwoofer PWM Outputs clocks from external sources. The TAS5716 operates • AM Interference Avoidance Support at a 384-kHz switching rate for 32-, 48-, 96-, and 192-kHz data, and at a 352.8 kHz switching rate for • Audio/PWM Processing 44.1-, 88.2-, and 176.4-kHz data. The 8× – Independent Channel Volume Controls With oversampling combined with the fourth-order noise 24-dB to –100-dB Range—Soft Mute (50% shaper provides a flat noise floor and excellent Duty Cycle) dynamic range from 20 Hz to 20 kHz. – Programmable Dynamic Range Control – 16 Programmable Biquads for Speaker Equalization – Adaptive Biquad Coefficients for EQ and DRC Filters – Programmable Input and Output Mixers 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 Digital is a trademark of Texas Instruments. 3 All other trademarks are the property of their respective owners.
