The TAS6424MSQ1EVM evaluation module (EVM) showcases the TAS6424MS, a 2.1-Mhz 4-channel digital input class-D audio solution for automotive infotainment. The 2.1-Mhz switching frequency allows users to significantly reduce inductor size and cost and optimize total system cost. TAS6424MS delivers 25 W (10% THD+N) per channel into 4-Ω with a 14.4-V supply. TAS6424MS’s wide supply voltage capabilities, from 4.5-V to 26-V, makes it ideal for head unit and external amplifier systems while delivering top-of-the-line performance during start-stop low-voltage transient events.
