SiP Chip for Independent DAC and AMP: MA2430

Questyle Technology, in collaboration with strategic partner USI, embarked on a two-year journey, starting in 2021, to develop of a series of chips in pursuit of an uncompromising auditory experience. The MA2430 incorporates Current Mode Amplification in the entire chain of lossless audio signal processing. Operating at a minimum voltage of 2V, the system requires only 3mA of operating current – half the power consumption of a typical TWS IEM.

However the MA2430 boasts the DAC capabilities for master tape-level music up to 192k and the performance of driving headphones with ultra low distortion at 0.00002%, challenging the physical limits of testing with top-tier audio analyzers.
