TAS5708
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.
Key Features
- Audio Input/Output - 20-W Into an 8-Ω Load From an 18-V Supply - Wide PVCC Range (10 V to 26 V); 3.3 V Digital Supply - Supports One Serial Audio Input (8 kHz - 48 kHz Sample Rates) (LJ/RJ/I2S) - Power-Stage Feedback Allows Operation From Poorly Regulated Power Supplies
- Audio/PWM Processing - Factory-Trimmed Internal Oscillator for Automatic Rate Detection - High-End 32-Bit Data Path Audio Processor - 14 Biquads for Speaker EQ - Dynamic Range Control (DRC)
- Benefits - EQ: Speaker Equalization Improves Audio Performance - DRC: Enables Speaker Protection and Night-Mode Listening. - Autobank Switching: Preloaded Coefficients 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
