basic information
- Supports audio output using the energy-efficient "CRI D-Amp Driver." The unique output method reduces power consumption to about half compared to typical Class D amplifiers when outputting at the same volume. - Achieves multi-channel output with a single chip. By utilizing 2 to 4 PWM outputs built into a general-purpose microcontroller, it can output one channel of audio, enabling multi-channel output with a single chip. - Low noise and high sound quality brought by a unique output method. The differential drive reduces noise during speaker output. Additionally, no current flows to the speakers during silence, resulting in only residual noise at the measurement limit level. - Reduced risk through the use of general-purpose components and fewer parts. Audio processing and output are achieved using a general-purpose single chip plus an H-bridge circuit, composed of general-purpose components. - Acoustic system developed with low code. A comprehensive set of GUI tools is available to support the design of acoustic systems. From configuring DSP to creating block diagrams of peripheral circuits, the design work is completed on the GUI. - Flexibility in development and technology inheritance. Developing with the GUI tools facilitates flexible development and easier technology transfer.
