TAS5701
Description
The TAS5701 is a 20-W efficient, digital audio power amplifier for driving stereo bridge-tied speakers. Two serial data inputs support up to 3 discrete audio channels.
Key Features
- Audio Input/Output - 20-W Into an 8-Ω Load From an 18-V Supply - Wide PVDD Range (0 V to 21 V) - Efficient Class-D Operation Eliminates Need for Heat Sinks - Two Serial Audio Inputs (3 Audio channels) - Supports 32-kHz to 192-kHz Sample Rates (LJ/RJ/I2S) - Line-Level Subwoofer PWM Outputs
- Audio/PWM Processing - BD (Filter-free) Modulation Supporting Bridge-Tied Loads ONLY - 4-Step Volume Control (0 dB, 6 dB, 12 dB, 18 dB) - All Channels Share Same Control - Soft Mute (50% Duty Cycle) - DC Blocking Filters - Fixed Maximum Modulation Limit At 97.7% - ≥100-dB SNR - Measured at Maximum Output With THD+N = 1%, 1 kHz, A-Weighted Noise, Gain = 0 dB - THD < 0.1% at 1/2 Rated Power
- General Features - 5-V Tolerant Inputs (See pin list for details on which inputs are 5-V tolerant) - Shutdown Mode for Low Power Consumption - Thermal and Short-Circuit Protection - Autodetect: Automatically Detect Sample-Rate Changes - No Need for External Microprocessor Intervention
