They provide four channels at 23 W • Load Diagnostic Functions: continuously into 4 Ω at less than 1% THD+N from a – Output Open and Shorted Load 14.4-V supply. Each channel can also deliver 38 W – Output-to-Power and -to-Ground Shorts into 2 Ω at 1% THD+N. The TAS5414B-Q1 uses single-ended analog inputs, while the TAS5424B-Q1 – Patented Tweeter Detection employs differential inputs for increased immunity to • Protection and Monitoring Functions: common-mode system noise. The digital PWM – Short-Circuit Protection topology of the device provides dramatic improvements in efficiency over traditional linear – Load-Dump Protection to 50 V amplifier solutions. This reduces the power dissipated – Fortuitous Open Ground and Power by the amplifier by a factor of ten under typical music Tolerant playback conditions. The device incorporates all the – Patented Output DC Level Detection While functionality needed to perform in the demanding Music Playing OEM applications area. They have built-in load diagnostic functions for detecting and diagnosing – Over-temperature Protection misconnected outputs to help to reduce test time – Over- and Undervoltage Conditions during the manufacturing process. – Clip Detection 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.
