USB-HEAR – USB High-end Audio Receiver

Application      Features      Supported Microcontroller & Licensing      


USB-HEAR is a microcontroller-based USB audio receiver solution for HiFi DAC and amplifier applications. It is implemented as a system on module (SoM) which enables easy and rapid integration.


The receiver implements a USB audio class 2.0 compliant PCM and DSD playback interface compatible with Windows, macOS and Linux hosts. For Windows, a bit-perfect, high-res audio driver is available.


For proper integration with a DAC, the module supports an external master clock input. The receiver can be controlled and monitored through an I2C register interface and a set of control and status lines.
