Description
The TAS5710 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-WInto an 😯 Load From an 18-V Supply
- Wide PVCC Range (10 V to 26 V)
- Supports One Serial Audio Input (8 kHz – 48 kHz Sample Rates) (LJ/RJ/I2S)
- Power-Stage Feedback Allows Operation From Poorly Regulated Power Supplies
- Factory-Trimmed Internal Oscillatorfor Automatic Rate Detection
- High-End 32-Bit Data Path Audio Processor
- 18 Biquads for Speaker EQ
- Dynamic Range Control (DRC)
- Support for Pseudo Bass and 3D Effects
- EQ: Speaker Equalization for Better Sound
- 2-Band DRC: Improved Bass Performance, Enables Speaker Protection and Night mode Listening
- Autobank Switching: PreloadedCoefficients for Three Different Sample Rates Eliminates the Need to Update Coefficients When Sample Rate Changes
- Autodetect: Automatically Detects Sample-Rate Changes Eliminating the Need for External Microprocessor Intervention
- Closed-Loop Power Stage: Enables Wide PVCC Operating Range and Reduced Power Supply Ripple Distortion
