Product Details

The ADAU1860 is a codec with three inputs and one output that incorporates two digital signal processors (DSPs). The path from the analog input to the DSP core to the analog output is optimized for low latency and is ideal for noise canceling earphone. With the addition of just a few passive components, the ADAU1860 provides a complete earphone solution.

APPLICATIONS

  • Noise canceling handsets, headsets, and headphones
  • Bluetooth active noise canceling (ANC) handsets, headsets, and headphones
  • Personal navigation devices
  • Digital still and video cameras
  • Musical instrument effect processors
  • Multimedia speaker systems
  • Smartphones

Lark Studio (Rev. 2.3.0)

Lark Studio is a standalone Windows Graphical User Interface (GUI) tool for programing and tuning software on the Lark/Lark-Lite/SSM6515. Lark Studio includes intuitively reading/writing control registers, and providing a drag and drop interface for user to design FastDSP schematic, which can be downloaded to the target directly. It also supports safe loading, generating C source files, calculating tables of filter coefficients and visualizing filter magnitude & phase response. It also supports EQ configuration, along with calculating tables of filter coefficients and visualizing filter magnitude & phase response, generating C source files, and download to the target.
