TAS5706A

The TAS5706A/B is a 20-W, efficient, digital audio power amplifier for driving stereo bridged-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, accepting a wide range of input data and clock rates. A fully programmable data path allows these channels to be routed to the internal speaker drivers or output via the subwoofer or headphone PWM outputs.

Features of the TAS5706A/B are:(1)Audio Input/Output 20-W into an 8- Load From an 18-V Supply Two Serial Audio Inputs (Four Audio Channels); (2)TAS5706A Supports: 2-Ch Bridged Outputs (20 W * 2)TAS5706B Supports: 2-Ch Bridged Outputs (20 W * 2) 4-Ch Single-Ended Outputs (10 W * 4) 2-Ch Single-Ended + 1-Ch Bridged (2.1 Mode) (10 W * 2 + 20 W); (3)Supports 32-kHz 192-kHz Sample Rates(LJ/RJ/I2S); (4)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 Constant Output Power Over Variation in Supply ; (5)Wide PVCC Range From (10 V to 26 V) No Separate Supply Required for Gate Drive.

The absolute maximum ratings of the TAS5706A/B 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.
