SLOS570–DECEMBER 2008 20-W STEREO DIGITAL AUDIO POWER AMPLIFIER WITH EQ/DRC and FEEDBACK 1 FEATURES • Audio Input/Output • Benefits – 20-W Into an 8-Ω Load From an 18-V Supply – EQ: Speaker Equalization Improves Audio Performance – Wide PVCC Range (10 V to 26 V); 3.3 V Digital Supply – DRC: Enables Speaker Protection and Night-Mode Listening. – Supports One Serial Audio Input (8 kHz - 48 2 kHz Sample Rates) (LJ/RJ/I S) – Autobank Switching: Preloaded Coefficients for Three Different Sample – Power-Stage Feedback Allows Operation Rates Eliminates the Need to Update From Poorly Regulated Power Supplies Coefficients When Sample Rate Changes • Audio/PWM Processing – Autodetect: Automatically Detects – Factory-Trimmed Internal Oscillator for Sample-Rate Changes Eliminating the Need Automatic Rate Detection for External Microprocessor Intervention – High-End 32-Bit Data Path Audio Processor – Closed-Loop Power Stage: Enables Wide – 14 Biquads for Speaker EQ PVCC Operating Range and Reduced – Dynamic Range Control (DRC) Power Supply Ripple Distortion DESCRIPTION The TAS5708 is a 20-W, efficient, digital audio power amplifier for driving stereo bridge-tied speakers. A 32-bit datapath eliminates the need for pre-scaling before processing and preserves signal integrity without sacrificing dynamic range. A digital audio processor with fully programmable digital filters allows designers to custom tune speakers for optimum sound in small enclosures. A programmable DRC can adjust power levels for a scaleable design while also enabling night-mode listening modes. The closed-loop architecture allows the device to operate from poorly regulated supplies. Figure 1 below shows the benefit of the feedback architecture when a noisy supply (1kHz, 500mVpp ripple) modulates a 10kHz audio input. The figure shows a 40dB improvement in sideband suppression when compared to an open-loop design. This correlates directly to a 24dB improvement in distortion as seen in Figure 2. 20 10 Fundamental Closest Open-Loop Closest Open-Loop Audio Input Competitor Competitor 0 TI Closed-Loop TI Closed-Loop −20 nd 2 Order Sideband 1 −40 40 dB rd Inprovement 3 Order Sideband −60 −80 0.1 −100 −120 Audio Input = 10 kHz P = 3 W O Supply Ripple = 1 kHz, 500 mVpp Supply Ripple = 1 kHz, 500 mVpp −140 0.01 5k 6k 7k 8k 9k 10k 12k 15k 20k 20 100 1k 10k 20k f − Frequency − Hz f − Frequency − Hz G018 G019 Figure 1.
