1 / 48 page  1 FEATURES APPLICATIONS DESCRIPTION TAS5414A, TAS5424A SLOS535A – JULY 2007 – REVISED FEBRUARY 2008 www.ti.com FOUR-CHANNEL AUTOMOTIVE DIGITAL AMPLIFIERS • 44-Pin PSOP3 (DKD) Power SOP Package With Heat Slug Up for the TAS5424A • TAS5414A – Single-Ended Input • 64-Pin QFP (PHD) Power Package With Heat • TAS5424A – Differential Input Slug Up for TAS5414A and TAS5424A • Four-Channel Digital Power Amplifier • Designed for Automotive EMC Requirements • Four Analog Inputs, Four BTL Power Outputs • AECQ100 Compliant • Typical Output Power per Channel at 10% • ISO9000:2002 TS16949 Certified THD+N • –40°C to 105°C Ambient Temperature Range – 28 W/Ch Into 4 Ω at 14.4 Vdc – 45 W/Ch Into 2 Ω at 14.4 Vdc – 58 W/Ch Into 4 Ω at 21 Vdc • High-Power OEM/Retail Head Units and – 116 W/Ch Into 2 Ω at 21 Vdc PBTL Amplifier Modules Where Feature Densities and System Configurations Require Reduction • Channels Can Be Paralleled (PBTL) for 1-Ω in Heat From the Audio Power Amplifier Applications • THD+N < 0.02%, 1 kHz, 1 W Into 4 Ω • Patented Pop- and Click-Reduction The TAS5414A and TAS5424A are four-channel Technology digital audio amplifiers designed for use in automotive – Soft Muting With Gain Ramp Control head units and external amplifier modules. The – Common-Mode Ramping TAS5414A and TAS5424A provide four channels at 23 W continuously into 4 Ω at less than 1% THD+N • Patented AM Interference Avoidance from a 14.4-V supply. Each channel can also deliver • Patented Cycle-by-Cycle Current Limit 38 W into 2 Ω at 1% THD+N. The TAS5414A uses • 75-dB PSRR single-ended analog inputs, while the TAS5424A • Four-Address I2C Serial Interface for Device employs differential inputs for increased immunity to common-mode system noise. The digital PWM Configuration and Control topology of the TAS5414A and TAS5424A provides • Configurable Channel Gains: 12-dB, 20-dB, dramatic improvements in efficiency over traditional 26-dB, 32-dB linear amplifier solutions. This reduces the power • Load Diagnostic Functions: dissipated by the amplifier by a factor of ten under typical music playback conditions. High efficiency is – Output Open and Shorted Load accomplished without the need for complicated – Output-to-Power and -to-Ground Shorts power-supply schemes. Multiple TAS5414As or – Patented Tweeter Detection TAS5424As can be synchronized to meet high-channel-count applications. • Protection and Monitoring Functions: – Short-Circuit Protection The TAS5414A and TAS5424A incorporate all the functionality needed to perform in the demanding – Load-Dump Protection to 50 V OEM applications area. They have built-in load – Fortuitous Open Ground and Power diagnostic functions for detecting and diagnosing Tolerant misconnected outputs to help to reduce test time – Patented Output DC Level Detection While during the manufacturing process. Music Playing – Overtemperature Protection – Over- and Undervoltage Conditions – Clip Detection • 36-Pin PSOP3 (DKD) Power SOP Package With Heat Slug Up for the TAS5414A 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
