The TAS5414A and TAS5424A are four-channel digital audio amplifiers designed for use in the automotive body and external amplifier modules. The TAS5414A and TAS5424A provide less than 1% THD+N from 14.4-V power supply with four channels at 23 W at 4 Ω continuously. Each channel can also deliver 38 W to 2Ω with 1% THD+N The TAS5414A uses a single-ended analog input, while TAS5424A increases immunity by adopting a differential input of common-mode system noise. The TAS5414A and TAS5424A topologies of digital PWM provide a significant increase in efficiency over traditional linear amplifier solutions. This reduces the power consumed by a factor amplifier typically under ten music playback conditions.
