The TAS6754-Q1 evaluation module (EVM) showcases the TAS6754-Q1, an automotive, four-channel, digital-input closed-loop class-D audio amplifier with 1L modulation that removes 1x inductor per channel and reduces inductor costs by 50% for four channels. The TAS6754-Q1 has an integrated DSP that supports many features such as real-time load diagnostics, current sense, an optional low-latency audio path for ANC/RNC, and advanced protection features like PVDD and thermal gain foldback. The EVM uses the PurePathTM Console (PPC3) graphical user interface (GUI) in the programming and I2C configuration to evaluate features, functionality and performance of the TAS6754-Q1 device.
Features
- Onboard USB to I2C controller to use the PPC3 GUI for device evaluation and configuration of features like real-time load diagnostics, thermal gain and PVDD foldback, and gain compensation biquads
- New 1L modulation requiring only one inductor per channel for cost savings and smaller PCB footprint compared to traditional solutions
- Optional low latency signal path for each channel to enable time-sensitive active noise cancellation (ANC) and road noise cancellation (RNC) applications
- Global temperature, channel temperature, and PVDD values through I2C readout for easy system-level thermal management
- Optical, SPDIF, USB and PSIA (external I2S/TDM) input options
