Overview

The TAS6422Q1EVM showcases the first true 2.1Mhz 2-Ch Digital Input Class-D Audio Solution for Automotive Infotainment in the market.  TAS6422’s 2.1-Mhz switching frequency allows customers to significantly reduce inductor size and cost and optimize total system cost.  TAS6422 delivers 25W (10% THD+N) per channel into 4-Ω with a 14.4-V supply.  TAS6422’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.  TAS6422 integrates I2C diagnostics and protection to match and surpass the highest standards for automotive quality and reliability.  TAS6422 CISPR25-L5 compliant EMC performance simplifies system design, lowers development cost and accelerates time-to-market delivery. 

TAS6422 EVM features: Optical SPDIF, USB and PSIA (external I2S) input options and On-board USB-I2C controller for GUI driven EVM evaluation.
