TAS5704

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. A hardware configurable data path allows these channels to be routed to the internal speaker drivers or output via the subwoofer PWM outputs.

Features of the TAS5704 are:(1)Audio Input/Output 20-W into an 8-? Load From an 18-V Supply Two Serial Audio Inputs (Four AudioChannels) 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); (2)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; (3)Wide PVCC Range From (10 V to 26 V); (4)Supports 32-kHz192-kHz (DVD-Audio) Sample Rates (LJ/RJ/I2S); (5)Line-Level Subwoofer PWM Outputs; (6)Audio/PWM Processing (Hardware Controlled) 4-Step Gain Control (-3dB, 3dB, 9dB, 12dB) Soft Mute Control (50% Output Duty Cycle); (7)Factory-Trimmed Internal Oscillator Enables Automatic Detection of Incoming Sample Rates.

The absolute maximum ratings of the TAS5704 can be summarized as:(1)Input clamp current, IIK (VI < 0 or VI > 1.8 V) :±20 mA; (2)Output clamp current, IOK (VO < 0 or VO > 1.8 V): ±20 mA; (3)Operating free-air temperature :0 to 85 °C; (4)Operating junction temperature range: 0 to 150 °C; (5)Storage temperature range, Tstg :40 to 125 °C.
