The TAS5414 and TAS5414A are four-channel digital audio amplifiers designed for use in automotive head units and external amplifier modules. The TAS5414A and TAS5414 provide four channels at 23 W continuously into 4 ohm at less than 1% THD+N from a 14.4-V supply. Each channel can also deliver 38 W into 2 ohm at 1% THD+N. The digital PWM topology of the TAS5414A and TAS5414 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. Multiple TAS5414As or TAS5414s can be synchronized to meet high-channel-count applications.
The TAS5414A incorporates all the functionality needed 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.
