Applications Information
POWER SUPPLIES
While the pins of the TP3060 family are well protected
against electrical misuse, it is recommended that the stan-
dard CMOS practice be followed, ensuring that ground is
connected to the device before any other connections are
made. In applications where the printed circuit board may be
plugged into a ‘‘hot’’ socket with power and clocks already
present, an extra long ground pin in the connector should
be used.
All ground connections to each device should meet at a
common point as close as possible to the GNDA pin. This
minimizes the interaction of ground return currents flowing
through a common bus impedance. 0.1
m
F supply decou-
pling capacitors should be connected from this common
ground point to V
CC
and V
BB
, as close to the device as
possible.
For best performance, the ground point of each CODEC/
FILTER on a card should be connected to a common card
ground in ‘‘STAR’’ formation, rather than via a ground bus.
This common ground point should be decoupled to V
CC
and
V
BB
with 10
m
F capacitors.
