Audio Amp Speaker 1-CH Mono/2-CH Stereo/4-CH Stereo 90W Class-D 64-Pin HTQFP EP Tray, TAS5414ATPHDQ1, Texas Instruments

The TAS5414A and TAS5424A are four-channel digital audio amplifiers designed for use in automotive head units and external amplifier modules. The TAS5414A and TAS5424A provide four channels at 23 W continuously into 4 O at less than 1% THD+N from a 14.4-V supply. Each channel can also deliver 38 W into 2 O at 1% THD+N. The TAS5414A uses single-ended analog inputs, while the TAS5424A employs differential inputs for increased immunity to common-mode system noise. The digital PWM topology of the TAS5414A and TAS5424A provides dramatic improvementsin efficiency over traditional linear amplifier solutions. This reduces the power dissipated by the amplifier by a factor of ten under typical music playback conditions. The TAS5414A and TAS5424A incorporate all the functionalityneeded to perform in the demanding OEM applications area. They have built-in load diagnostic functions for detecting and diagnosing misconnected outputs to help to reduce test time during the manufacturing process.
