Audio LSIs

Special focus - ML2620 Speaker Amplifier with "LoudSound" technology

ML2620 - Speaker Amplifier Latest in the series of Audio LSIs is the ML2620,a monaural speaker amplifier with OKI´s "LoudSound"technology which are best used in small and thin portable devices.
The ML2620 adopts OKI's proprietary signal processing technology, and with speakers a mere 10mm-20mm in diameter, it can replay music with approximately twice the volume of conventional OKI models. It can also correct the volume and sound quality to optimize them for each device as it extracts the parameters for acoustic-effect characteristics.
