Product Summary

The TAS5414TDKDQ1 is a four-channel digital audio amplifier designed for use in automotive head units and external amplifier modules. The TAS5414TDKDQ1 provides four channels at 23 W continuously into 4 W at less than 1% THD+N from a 14.4-V supply. Each channel can also deliver 38 W into 2 W at 1% THD+N. The TAS5414TDKDQ1 uses single-ended analog inputs for increased immunity to common-mode system noise. The digital PWM topology of the TAS5414TDKDQ1 provides dramatic improvements in efficiency over traditional linear amplifier solutions. This reduces the power dissipated by the amplifier by a factor of ten under typical music playback conditions. High efficiency is accomplished without the need for complicated power-supply schemes. The TAS5414TDKDQ1 can be synchronized to meet high-channel-count applications.
