1 / 63 page  TAS5713 www.ti.com SLOS637 – DECEMBER 2009 25-W DIGITAL AUDIO POWER AMPLIFIER WITH EQ AND DRC Check for Samples: TAS5713 1 FEATURES 2 • Audio Input/Output • Benefits – 25-W Into an 8- Ω Load From a 20-V Supply – EQ: Speaker Equalization Improves Audio Performance – Wide PVDD Range, From 8 V to 26 V – DRC: Dynamic Range Compression. Can – Supports BTL Configuration With 4- Ω Load Be Used As Power Limiter. Enables – Efficient Class-D Operation Eliminates Speaker Protection, Easy Listening, Need for Heatsinks Night-Mode Listening – One Serial Audio Input (Two Audio – Autobank Switching: Preload Coefficients Channels) for Different Sample Rates. No Need to – I2C Address Selection Pin (Chip Select) Write New Coefficients to the Part When – Single Output Filter PBTL Support Sample Rate Changes – Supports 8-kHz to 48-kHz Sample Rate – Autodetect: Automatically Detects (LJ/RJ/I2S) Sample-Rate Changes. No Need for • Audio/PWM Processing External Microprocessor Intervention – Independent Channel Volume Controls With DESCRIPTION Gain of 24 dB to Mute – Programmable Two-Band Dynamic-Range The TAS5713 is a 25-W, efficient, digital-audio power amplifier for driving stereo bridge-tied speakers. One Control serial data input allows processing of up to two – 22 Programmable Biquads for Speaker EQ discrete audio channels and seamless integration to and Other Audio-Processing Features most digital audio processors and MPEG decoders. – Programmable Coefficients for DRC Filters The device accepts a wide range of input data and data rates. A fully programmable data path routes – DC Blocking Filters these channels to the internal speaker drivers. • General Features The TAS5713 is a slave-only device receiving all – I2C Serial Control Interface Operational clocks from external sources. The TAS5713 operates Without MCLK with a PWM carrier between a 384-kHz switching rate – Requires Only 3.3 V and PVDD and a 352-KHz switching rate, depending on the input – No External Oscillator: Internal Oscillator sample rate. Oversampling combined with a for Automatic Rate Detection fourth-order noise shaper provides a flat noise floor and excellent dynamic range from 20 Hz to 20 kHz.. – Surface-Mount, 48-Pin, 7-mm × 7-mm HTQFP Package – Thermal and Short-Circuit Protection – 106-dB SNR, A-Weighted – AD and BD PWM-Mode Support – Up to 90% Efficient A 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 PowerPad is a trademark of Texas Instruments.
