TAS5707
Description
The TAS5707 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 digital audio processors and MPEG decoders.
Key Features
- 23 Audio Input/Output - 20-W Into an 8-Ω Load From an 18-V Supply - Wide PVDD Range, From 8 V to 26 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 Dynamic Range Control - 14 Programmable Biquads for Speaker EQ and Other Audio Processing Features - Programmable Coefficients for DRC Filters - DC Blocking Filters
- 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 - 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
