Description for the TAS5414C
The TAS5414C is a four-channel Class-D audio amplifier designed for use in automotive head units and external amplifier modules. It provides four channels at 23 W continuously into 4 Ω at less than 1% THD+N from a 14.4-V supply. Each channel can also deliver 38 W into 2 Ω at 1% THD+N. The TAS5414C uses single-ended analog inputs. The class-D PWM topology of the device 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. The device has a built-in load diagnostic functions for detecting and diagnosing misconnected outputs to help to reduce test time during the manufacturing process.
