Power and Ground Pins
V
CCA
, V
CCD
(Voltage Inputs)
To minimize noise, the analog and digital circuits in the ISD5116 device use separate power busses.
These +3 V busses lead to separate pins. Tie the V
CCD
pins together as close as possible and
decouple both supplies as near to the package as possible.
V
SSA
, V
SSD
(Ground Inputs)
The ISD5116 series utilizes separate analog and digital ground busses. The analog ground (V
SSA
)
pins should be tied together as close to the package as possible and connected through a low-
impedance path to power supply ground. The digital ground (V
SSD
) pin should be connected through a
separate low impedance path to power supply ground. These ground paths should be large enough to
ensure that the impedance between the V
SSA
pins and the V
SSD
pin is less than 3. The backside of
the die is connected to V
SSD
through the substrate resistance. In a chip-on-board design, the die
attach area must be connected to V
SSD
.
NC (Not Connect)
These pins should not be connected to the board at any time. Connection of these pins to any signal,
ground or V
CC,
may result in incorrect device behavior or cause damage to the device.
7.6.4. Sample PC Layout
The SOIC package is illustrated from the top. PC board traces and the three chip capacitors are on
the bottom side of the board.

Note 1: V
SSD
traces should be kept
separated back to the V
SS
supply feed
point..
Note 2: V
CCD
traces should be kept
separate back to the V
CC
Supply feed
point.
Note 3: The Digital and Analog grounds
tie together at the power supply. The
V
CCA
and V
CCD
supplies will also need
filter capacitors per good engineering
practice (typ. 50 to 100 uF).
