HIGH PERFORMANCE ELECTRONIC TONE CONTROL
TC9184AP is electronic tone control ICs developed for
audio equipment. These ICs can control bass and treble
with serial data externally.
FEATURES
0 Allows 13-step variable control lr-o---) by 2dB
o Bass and treble of 2 channels are built in.
0 Being in CMOS structure, wide dynamic ranges and low
distortion rate are obtained. DlP16-P-300-2.54A
o A dual power supply of (+) and (-) is applicable, and Weight : 1.00g (Typ.)
then the serial input data operates in a logic level of 0
to 5V, so the interface with a micro computer is easily
available.

DESCRIPTION ON OPERATION
1. Setting of tone control position
The tone control position can optionally be set by inputting specified data to DATA, CK, and STB
terminals.
Input data are composed of 20 bits in the following manner :
It Serial data format
DATA B T "0" +12 +10 +8 +6 +4 +2 0 -2 -4 -6 -8 -10-12 "1" "1" "1" "1"

BASS VOLUME
0 The 4th to the 16th DATA are tone control data and can be used for setting in 13 steps for the
range of 12--0---12dB.
o The 1st and the 2nd DATA are for selecting data of BASS VOLUME/TREBLE VOLUME.
When 3: 1, BASS VOLUME is set, T-- 1, TREBLE VOLUME, and B=T= 1, BASS+TREBLE VOLUME.
It Two channels of BASS/TREBLE VOLUME and change simultaneously.
(Note) The two channels of each BASS/TREBLE VOLUME can not be set independently.
o The received data are transffered into each volume synchronously to the rise of STB signals.

2. Input to DATA, CK, and STB
Although TC9184AP is usually used in a dual power supply of (+) and (-), DATA CK, and STB
terminals are operated only by the single power supply of (+) by means of a built-in level shift
circuit.
Furthermore, the threshold level of the input to these three terminals is designed to low, they can
be operated at a logical level of 5V.

3. Power supply and correlations
Although TC9184P is usually used in dual power supply, they can be operated even in a single
power supply, where it should be noted that when VDD-GND>9.0V, the threshold input voltage
level (VIH/VIL) at DATA, CK, and STB terminals becomes as follows :
