ML22Q234
Short-time Playback - Internal D-class Speaker Amplifier Type
ML22Q234/ML22Q244/ML22Q254 can easily play sound by simply entering a simple command from the MCU.
These have clock synchronous serial, stand-alone, and I2C interfaces to meet the needs of a wide range of customers.
In addition to the functions required for sound output, such as the high-quality sound and high-compression algorithm HQ-ADPCM, oscillation circuit, and 1W monaural class D speaker amplifier, it also has a function to rewrite sound data from the MCU.
The sound function can be easily realized simply by adding these LSIs.
