TAS5414C 4-Channel Class-D Audio Amplifier

Texas Instruments TAS5414C 4-Channel Class-D Audio Amplifier is designed for use in automotive head units and external amplifier modules. This device provides four channels at 23W continuously into 4Ω at less than 1% Total Harmonic Distortion plus Noise (THD+N) from a 14.4V supply. Each channel can also deliver 38W into 2Ω 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 feature reduces the power dissipated by the amplifier by a factor of ten under typical music playback conditions. The TAS5414C has built-in load diagnostic functions for detecting and diagnosing misconnected outputs to help to reduce test time during the manufacturing process.
