Left VCF Filter Cap Port.
Positive Supply.
Analog Common Voltage. In-
ternal Circuit Ground Point.
Must be held to a voltage ap-
proximately halfway between
V+ and V–. Should be a clean
low impedance voltage source
capable of at least 4 mA, such
as from a buffer driven off a
supply-splitting voltage divider.
Input to VCA Control Port.
Allows external adjustment of
attenuation with a +22 mV/dB
slope. Zero volts relative to
ACOM gives zero additional
attenuation. Should be con-
nected to ACOM if function
not required.
Input to VCF Detector.
Combined Left Plus Right
Output.
Input to VCA Detector.
Voltage Controlled Filter.
Time Constant Capacitor Port.
Voltage Controlled Amplifier.
Time Constant Capacitor Port.

Function and Explanation
13 NC
Make No Connection to this
Pin.
14 DEFAULT
THRESHOLD
Default Threshold Adjust-
ment Port. Allows reduction
of noise reduction action if
signal source is relatively
clean such as CD sources.
Normally connected to Analog
Common. –1.2 V is recom-
mended for CDs; –2 V com-
pletely defeats noise reduction.
15 AUTO THRESHOLD
CAP
Automatic Threshold Detec-
tor Capacitor Port.
16 DEFEAT
Logic High: Defeats Noise
Reduction.
Logic Low: Normal Action.
Connect to Ground if not used.
17 MUTE
Logic High: Mute.
Logic Low: Normal Action.
Connect to Ground if not used.
18 NC
Make no connection to this
pin.
19 DIGITAL GND
Digital Logic Reference
(Logic Zero).
20 V–
Negative Supply.
21 R VCF C2
Right VCF Capacitor Port.
22 R VCF C1

NOTE
1θJA is specified for the worst case conditions, i.e., θJA is specified for device in socket
for P-DIP packages; θJA is specified for device soldered onto a circuit board for
surface mount packages..
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the SSM2000 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
WARNING!
