BASH IC Amplifier

an entirely new concept

BASH IC Amplifier
By utilising a special processor and a variable step-down converter, STMicroelectronics in partnership with Indigo Manufacturing have succeeded in developing an integrated amplifier with remarkably high efficiency, without sacrificing audio quality.Audio enthusiasts are likely to have widely varying opinions on many different subjects, but they are also likely to agree on one thing. If they had the choice, they would prefer an amplifier that delivers perfect quality, is able to deliver quite a bit of power, and is physically as small as possible.This combination of characteristics is difficult to obtain in practice. Quality and power can be simultaneously realised. But a quality amplifier demands a sizeable power supply and a generous quiescent current in a Class AB design, for example (not to mention Class-A).
