Datasheet
DIGITAL CONTROLLED AUDIO PROCESSOR
GENERAL DESCRIPTION
The S1A0501X01 is an audio processor for volume/tone/fader
control, which is suitable for car radios or Hi-Fi system. It has a
built-in trimmer for user to set a source level. R/L rear output is
changable to input in the case of a home audio system for user
conveniency, an external equalizer or a noise reduction circuit
is selectable.
When the S1A0501X01 is used with some sound-effect equip-
ment such as graphic equalizer, the internal tone control block
of S1A0501X01 can be bypassed for decreasing redundancy.
All selections and function controls are designed to be con-
trolled by an I
interface protocol.
