SC5388
5-MODE PRESET EQUALIZER WITH BASS BOOSTER
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.
FEATURES
* Wide operating voltage range(VCC=5.0V ~ 11.0V)
* Low total harmonic distortion and high S/N ratio
(THD+N<0.02%, S/N > 95dB)
* LED display output mode
* Less external parts
* 5-sound selections provided
* Bass booster function
* Direct and cyclic key selection provided
* 2-Channel output

TREBLE AND BASS ADJUSTMENTS
It is general knowledge that different individuals have different listening preference. The application circuit of
SC5388 included in this specification has been designed for the taste general listening public; however, you can
make the necessary adjustment to suit your personal taste. Please refer to the Section below.
1. TREBLE ADJUSTMENT
The Treble adjustment is made by changing the value of the 2 capacitors connected between TL-OUTL, TR-
OUTR, Please refer to Fig. 6.
As the capacitor value becomes bigger, the treble of the gain frequency curve is shifted down. Likewise, as
the capacitor value become smaller, the treble gain frequency curve shifts the opposite direction. Referring to the
Fig.6. we see that at 6dB, different capacitor values exhibit different frequency response. Capacitor value 1800pF
has a lower frequency gain response than 1200pF capacitor.
2. BASS ADJUSTMENT
Bass adjustment can be made by changing the values of the capacitor connected between BL1~BL2 and
BR1~BR2. Please refer to Fig.7.
The larger the capacitor value used, the frequency response curve shifts down. Like wise, the smaller the
capacitor value, the frequency response curve shifts the opposite direction. In Fig.7, at 9dB different capacitor
value exhibit different frequency responses. A capacitor with a value of 0.1µF has smaller frequency response
than 0.56µF capacitor.

HANDLING MOS DEVICES:
Electrostatic charges can exist in many things. All of our MOS devices are internally protected against
electrostatic discharge but they can be damaged if the following precautions are not taken:
• Persons at a work bench should be earthed via a wrist strap.
• Equipment cases should be earthed.
• All tools used during assembly, including soldering tools and solder baths, must be earthed.
• MOS devices should be packed for dispatch in antistatic/conductive containers.
