TAS5705
Description
The TAS5705 is a 20-W, efficient, digital audio power amplifier for driving stereo bridge-tied speakers. Two serial data inputs allow processing of up to four 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 Power-Supply Range From (8 V to 23 V) - Efficient Class-D Operation Eliminates Need for Heat Sinks - Requires Only Two Power-Supply Rails - Two Serial Audio Inputs (Four Audio Channels) - Supports 32-kHz-192-kHz Sample Rates (LJ/RJ/I2S) - Headphone PWM Outputs - Subwoofer PWM Outputs
- Audio/PWM Processing - Independent Channel Volume Controls With 24-dB to -100-dB Range - Soft Mute (50% Duty Cycle) - Programmable Dynamic Range Control - 16 Adaptable Biquads for Speaker EQ - Seven Biquads for Left and Right Channels - Two Biquads for Subwoofer Channel - Adaptive Coefficients for DRC Filters - Programmable Input and Output Mixers - DC Blocking Filters - Loudness Compensation for Subwoofer - Automatic Sample Rate Detection and Coefficient Banking for DRC and EQ
- General Features - Serial Control Interface Operational Without MCLK - Factory-Trimmed Internal Oscillator Enables Automatic Detection of Incoming Sample Rates - Thermal and Short-Circuit Protection
- Benefits - EQ: Speaker Equalization Improves Audio Performance - DRC: Dynamic Range Compression. Enables Power Limiting, Speaker Protection, Easy Listening, Night-Mode Listening - Autobank Switching: Preload Coefficients for Different Sample Rates. No Need to Write Any Coefficients to the Part When Sample Rate Changes. - Autodetect: Automatically Detects Sample-Rate Changes. No Need for External Microprocessor Intervention
