5-MODE PRESET EQUALIZER IC
DESCRIPTION
The SC5388 is a 2-channel digital preset equalizer utilizing
CMOS technology. It provides 5 different sound selections, namely:
Flat/normal, rock, Pops, Classic and Jazz. A Bass Booster may be
added any of 5 sound selections, thereby creating more audio
versatility. SC5388 provides two types of key selection mode
namely: the Direct and the Cyclic. Pin assignment and application
circuit are optimized for cost saving advantages and easy PCB
layout.

FUNCTIONAL DESCRIPTION
The SC5388 is a 2-channel and 5-Mode digital preset equalizer with a Bass Booster function. It provides two
types of key selection mode namely: the Direct and the Cyclic. These two key selection Modes are determined by
SEL pin. Please refer to the table below:
Key Selection Mode SEL Pin Description
Press FLAT key to activate Flat Mode
Press ROCK key to activate Rock Mode
Direct Low
Cyclic Floating/High
Note: 1). The Bass Booster can be controlled in the same manner under the Direct or the Cyclic Key selection
Mode. To turn the Bass Booster ON or OFF, press the BB Key.
2). Under the Cyclic Selection mode, press the CYC Key, to go to the next sound selection.
Press POPS key to activate Pops Mode
Press CLASSIC key to activate Classic Mode
Press JAZZ key to activate Jazz Mode
