1 / 68 page  TAS5717 TAS5719 www.ti.com SLOS655A – NOVEMBER 2010 – REVISED FEBRUARY 2011 10-W/15-W Digital Audio Power Amplifier with Integrated Cap-Free HP Amplifier Check for Samples: TAS5717, TAS5719 1 FEATURES 2 • Audio Input/Output • Benefits – TAS5717 Supports 2×10 W and TAS5719 – EQ: Speaker Equalization Improves Audio Supports 2 ×15 W Output Performance – Wide PVDD Range, From 4.5 V to 26 V – DRC: Dynamic Range Compression. Can Be Used As Power Limiter. Enables – Efficient Class-D Operation Eliminates Speaker Protection, Easy Listening, Need for Heatsinks Night-Mode Listening – Requires Only 3.3 V and PVDD – DirectPath Technology: Eliminates Bulky – One Serial Audio Input (Two Audio DC Blocking Capacitors Channels) – Stereo Headphone/Stereo Line Drivers: – I2C Address Selection via PIN (Chip Select) Adjust Gain via External Resistors, – Supports 8-kHz to 48-kHz Sample Rate Dedicated Active Headpone Mute Pin, High (LJ/RJ/I2S) Signal-to-Noise Ratio – External Headphone-Amplifier Shutdown – Two-Band DRC: Set Two Different Signal Thresholds for Low- and High-Frequency – Integrated CAP-Free Headphone Amplifier Content – Stereo Headphone (Stereo 2-V RMS Line Driver) Outputs DESCRIPTION • Audio/PWM Processing The TAS5717/TAS5719 is a 10-W/15-W, efficient, digital audio-power amplifier for driving stereo – Independent Channel Volume Controls With bridge-tied speakers. One serial data input allows 24-dB to Mute processing of up to two discrete audio channels and – Programmable Two-Band Dynamic Range seamless integration to most digital audio processors Control and MPEG decoders. The device accepts a wide – 14 Programmable Biquads for Speaker EQ range of input data and data rates. A fully programmable data path routes these channels to the – Programmable Coefficients for DRC Filters internal speaker drivers. – DC Blocking Filters The TAS5717/9 is a slave-only device receiving all – 0.125-dB Fine Volume Support clocks from external sources. The TAS5717/TAS5719 • General Features operates with a PWM carrier between a 384-kHz – Serial Control Interface Operational Without switching rate and a 352-KHz switching rate, MCLK depending on the input sample rate. Oversampling combined with a fourth-order noise shaper provides a – Factory-Trimmed Internal Oscillator for flat noise floor and excellent dynamic range from Automatic Rate Detection 20 Hz to 20 kHz. – Surface Mount, 48-Pin, 7-mm × 7-mm HTQFP Package – AD, BD, and Ternary PWM-Mode Support – Thermal and Short-Circuit Protection 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 FilterPro is a trademark of Texas Instruments.
