Texas Instruments  TAS5424CTDKERQ1

The TAS5414C-Q1 and TAS5424C-Q1 are four-channel digital audio amplifiers designed for use inautomotive head units and external amplifier modules. They providefour channels at 23 W continuously into 4 Ω at less than 1% THD+N from a 14.4-V supply. Eachchannel can also deliver 38 W into 2 Ω at 1% THD+N. The TAS5414C-Q1uses single-ended analog inputs, whereas the TAS5424C-Q1 employsdifferential inputs for increased immunity to common-mode system noise. The digital PWMtopology of the device provides dramatic improvements in efficiency over traditional linearamplifier solutions. This reduces the power dissipated by the amplifier by a factor of ten undertypical music playback conditions. The device incorporates all the functionality needed to performin the demanding OEM applications area. The devices have built-in load diagnostic functions fordetecting and diagnosing misconnected outputs to help to reduce test time during the manufacturingprocess.
