General Description
The ML2620 is a speaker amplifier using OKI´s unique "LOUDNESS" signal processing technology which can
optimize volume for small speakers without distortion and clipping noise. With the built-in ALC (Automatic Level
Controller), various acoustic parameters can be set to adopt to the characteristics of the environment and the application.
The ML2620 is the ideal speaker amplifier to play multi-media content from small speakers (10-20mm) as used in
mobile phones, personal navigation device (PND), digital still cameras (DSC) or portable TVs.
