TAS5704
Description
The TAS5704 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 accepting a wide range of input data and clock rates.
Key Features
- 2 Audio Input/Output - 20-W into an 8-Ω Load From an 18-V Supply - Two Serial Audio Inputs (Four Audio Channels) - Supports Multiple Output Configurations: - 2-Ch Bridged Outputs (20 W × 2) - 4-Ch Single-Ended Outputs (10 W × 4) - 2-Ch Single-Ended + 1-Ch Bridged (2.1) (10 W × 2 + 20 W)
- Closed Loop Power Stage Architecture - Improved PSRR Reduces Power Supply Performance Requirements - Higher Damping Factor Provides for Tighter, More Accurate Sound With Improved Bass Response - Lower EMC Emissions - Output Power is Independent of Supply Voltage Variation
- Wide PVCC Range From (10 V to 26 V)
- Supports 32-kHz-192-kHz (DVD-Audio) Sample Rates (LJ/RJ/I2S)
- Line-Level Subwoofer PWM Outputs
- Audio/PWM Processing (Hardware Controlled) - 4-Step Gain Control (-3dB, 3dB, 9dB, 12dB) - Soft Mute Control (50% Output Duty Cycle)
- Factory-Trimmed Internal Oscillator Enables Automatic Detection of Incoming Sample Rates
- Thermal and Short-Circuit Protection spacer
