TAS5424AEVM3

The TAS5424AEVM3 is an evaluation module for TAS5424A, a four channel digital audio amplifiers designed for use in automotive head units and external amplifier modules. The TAS5424A provide four channels at 23 W continuously into 4R at less than 1% THD+N from a 14.4V supply. Each channel can also deliver 38W into 2R at 1% THD+N. The TAS5424A employs differential inputs for increased immunity to common mode system noise. The digital PWM topology of the TAS5424A 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 TAS5424A incorporate 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.
