SLOS559 – JUNE 2008 20-W STEREO DIGITAL AUDIO POWER AMPLIFIER • General Features • Audio Input/Output – 5-V Tolerant Inputs (See pin list for details on which inputs are 5-V tolerant) – 20-W Into an 8- Ω Load From an 18-V Supply – Shutdown Mode for Low Power – Wide PVDD Range (0 V to 21 V) Consumption – Efficient Class-D Operation Eliminates – Thermal and Short-Circuit Protection Need for Heat Sinks – Autodetect: Automatically Detect – Two Serial Audio Inputs (3 Audio channels) Sample-Rate Changes – No Need for – Supports 32-kHz to 192-kHz Sample Rates External Microprocessor Intervention (LJ/RJ/I2S) – Line-Level Subwoofer PWM Outputs • Audio/PWM Processing The TAS5701 is a 20-W efficient, digital audio power – BD (Filter-free) Modulation Supporting amplifier for driving stereo bridge-tied speakers. Two Bridge-Tied Loads ONLY serial data inputs support up to 3 discrete audio channels. The SDIN1 input is routed to the internal – 4-Step Volume Control (0 dB, 6 dB, 12 dB, left and right outputs. The SDIN2 input is dedicated to 18 dB) the SUB_PWM± outputs. – All Channels Share Same Control The TAS5701 is a clock slave-only device receiving – Soft Mute (50% Duty Cycle) clocks from external sources. The TAS5701 operates – DC Blocking Filters at a 384-kHz switching rate for 32-, 48-, 96-, and – Fixed Maximum Modulation Limit At 97.7% 192-kHz data and 352.8-kHz switching rate 44.1-,88.2-, and 176.4-kHz data. The 8× – ≥100-dB SNR – Measured at Maximum oversampling combined with the fourth-order noise Output With THD+N = 1%, 1 kHz, shaper provides a flat noise floor and excellent A-Weighted Noise, Gain = 0 dB dynamic range from 20 Hz to 20 kHz. – THD < 0.1% at 1/2 Rated Power 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.
