They provide four channels at 23 W – 150 W/Ch Into 2 Ω at 24 V (PBTL) continuously into 4 Ω at less than 1% THD+N from a 14.4-V supply. Each channel can also deliver 38 W • Channels Can Be Paralleled (PBTL) for High- into 2 Ω at 1% THD+N. The TAS5414C-Q1 uses Current Applications single-ended analog inputs, whereas the TAS5424C- • THD+N < 0.02%, 1 kHz, 1 W Into 4 Ω Q1 employs differential inputs for increased immunity • Patented Pop- and Click-Reduction Technology to common-mode system noise. The digital PWM topology of the device provides dramatic – Soft Muting With Gain Ramp Control improvements in efficiency over traditional linear – Common-Mode Ramping amplifier solutions. This reduces the power dissipated • Patented AM Interference Avoidance by the amplifier by a factor of ten under typical music playback conditions. The device incorporates all the • Patented Cycle-by-Cycle Current Limit functionality needed to perform in the demanding • 75-dB PSRR OEM applications area. The devices have built-in • Four-Address I2C Serial Interface for Device load diagnostic functions for detecting and diagnosing Configuration and Control misconnected outputs to help to reduce test time during the manufacturing process. • Channel Gains: 12-dB, 20-dB, 26-dB, 32-dB • Load Diagnostic Functions: Device Information(1) – Output Open and Shorted Load PART NUMBER PACKAGE BODY SIZE (NOM) – Output-to-Power and -to-Ground Shorts TAS5414C-Q1 HTQFP (64) 14.00mm x 14.00mm – Patented Tweeter Detection TAS5424C-Q1 HSSOP (44) 3.50mm x 15.90mm • Protection and Monitoring Functions: (1) For all available packages, see the orderable addendum at the end of the datasheet. – Short-Circuit Protection – Load-Dump Protection to 50 V – Fortuitous Open-Ground and -Power Tolerant – Patented Output DC Level Detection While Music Playing – Overtemperature Protection – Over- and Undervoltage Conditions – Clip Detection • 44-Pin PSOP3 (DKE) Power SOP Package With Heat Slug Up for TAS5424C-Q1 • 64-Pin QFP (PHD) Power Package With Heat Slug Up for TAS5414C-Q1 • Designed for Automotive EMC Requirements • Qualified According to AEC-Q100 • ISO9000:2002 TS16949 Certified • –40°C to 105°C Ambient Temperature Range 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
