Function
1
GND
Ground
2
VCAIN
VCA Input Pin. A typical
connection is a 1 µF–10 µF
capacitor from the buffer output
pin (Pin 3) to this pin.
3
BUFOUT
Input Buffer Amplifier Output
Pin. Must not be loaded by
capacitance to ground.
4
AUDIO +IN
Input Audio Signal. The input
signal should be ac-coupled
(0.1 µF typical) into this pin.
5
AVG CAP
Detector Averaging Capacitor.
A capacitor, 2.2 µF–22 µF, to
ground from this pin is the
averaging capacitor for the
detector circuit.
6
COMP RATIO SET Compression Ratio Set Pin. A
resistor to ground from this pin
sets the compression ratio as
shown in TPC 1.
7
OUTPUT
Output Signal.
8
V+
Positive Supply, 5 V Nominal.
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 SSM2165 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.
