TAS5709A
Description
The TAS5709 is a 20-W, efficient, digital audio-power amplifier for driving stereo bridge-tied speakers. One serial data input allows processing of up to two discrete audio channels and seamless integration to most di.
Key Features
- Audio Input/Output - 20-W Into an 8-Ω Load From an 18-V Supply - Wide PVDD Range, From 8 V to 24 V - Efficient Class-D Operation Eliminates Need for Heatsinks - Requires Only 3.3 V and PVDD - One Serial Audio Input (Two Audio Channels) - Supports 8-kHz to 48-kHz Sample Rate (LJ/RJ/I2S)
- Audio/PWM Processing - Independent Channel Volume Controls With 24 dB to Mute - Soft Mute (50% Duty Cycle) - Programmable 2-Band Dynamic Range Control - 22 Programmable Biquads for Speaker EQ and Other Audio-Processing Features - Programmable Coefficients for DRC Filters - Programmable Input and Output Mixers - DC Blocking Filters - Support for 3D Effects - Pseudo Bass Support
- General Features - Serial Control Interface Operational Without MCLK - Factory-Trimmed Internal Oscillator for Automatic Rate Detection - Surface Mount, 48-Pin, 7-mm × 7-mm HTQFP Package - Thermal and Short-Circuit Protection
- Benefits - EQ: Speaker Equalization Improves Audio Performance - DRC: Dynamic Range Compression. Can Be Used As Power Limiter. Enables Speaker Protection, Easy Listening, Night-Mode Listening - Two-Band DRC: Sets Two Different Thresholds for Low- and High-Frequency Content - Autobank Switching: Preload Coefficients for Different Sample Rates. No Need to Write New Coefficients to the Part When Sample Rate Changes - Autodetect: Automatically Detects Sample-Rate Changes. No Need for External Microprocessor Intervention
