V
To minimize noise, the analog and digital circuits in the ISD5100 Series devices use separate power
busses. These +3 V busses lead to separate pins. Tie the V
decouple both supplies as near to the package as possible.
V
The ISD5100 Series utilizes separate analog and digital ground busses. The analog ground (V
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
separate low impedance path to power supply ground. These ground paths should be large enough to
ensure that the impedance between the V
