1 TAS5706 Hear the Difference! Industries 1 st Closed-Loop Digital-Input Class D Amplifier

2 Home Audio Amplifier Families TPA3000 Family 3-20W Stereo/Mono TPA3100 Family 10-40W Stereo/Mono TPA3120 Family 15-50W Stereo/Mono Single Ended TAS5700 Family 20W Digital-Input + Processing NEW! Class-D Milestones Shipped 1 st Class-D amp in 1998 Delivered over 900M amps to date Shipped to every flat panel TV manufacturer

3 TAS W Stereo Digital Amplifier with Integrated Feedback Volume Loudness BQ Full Bridge Serial Audio 7 BQ 2 BQ 7 BQ (L) (R) (SUB) DRC PWM Modulator Full Bridge PWM HP PWM Sub Output Mux Input Mux Bass Mgmt SDIN1 SDIN2 + 8Ω PWM Out I2C 2x Digital I/F’s (I2S or LJ/RJ) On Chip Audio Processing Speaker EQ (16 BQ’s), DRC Mixers, AM Avoid, Loudness, etc Wide Vcc Range (10 to 26V) Vdd Closed Loop Architecture Tighter, more accurate sound with improved Bass response Improved PSRR, EMC, etc. Head Phone & Sub outputs I2C control 10-26V Vcc 3.3V Vdd On-Chip DAP Output Configurations (40W Total) 2x 20W (BTL) Stereo 4x 10W (SE) Quad 2x 10W (SE) + 1x 20W (BTL) 2x 20W (BTL) + Ext PWM Sub 2.1

4 Closed Loop Advantages: Higher Damping Factor Greater PSRR Improved EMC Performance Constant Volume Levels

5 Greater PSRR High Quality Audio from a Low Quality Supply

6 Higher Damping Factor Tighter, More Accurate Sound with Improved Bass 3 cycle burst of an 80Hz signal

7 Higher Damping Factor Tighter, More Accurate Sound with Improved Bass

8 Improved EMC Less Board Spins, Quicker Time to Market

9 New Graphical Development Environment PurePath STUDIO
