This board supports: TAS2555YZEVMTAS2557EVM and TAS2559EVM.

The Smart Amplifier Speaker Characterization Board, when used in conjunction with a supported TI Smart Amplifier and PurePath Console software, provides users the ability to measure speaker excursion, temperature and other parameters for use with a TI Smart Amplifier products.  The entire solution provides an easy to use and step by step process to guide you through the entire speaker characterization process.  Once characterization is complete, the speaker parameters are then automatically loaded into PurePath Console so fine-tuning for optimal sound with speaker protection can begin.

  • Easily and quickly characterize speakers
  • Quick connection to TI Smart Amplifier EVMs
  • Microphone included for SPL measurements
  • Laser input for speaker excursion measurements
