APPLICATION INFORMATION
power supplies
While the terminals of the TP3056B device is well protected against electrical misuse, it is recommended that
the standard 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 can 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 device
ANLG GND terminal. This minimizes the interaction of ground return currents flowing through a common bus
impedance. V
CC
and V
BB
supplies should be decoupled by connecting 0.1-
μ
F decoupling capacitors to this
common point. These bypass capacitors must be connected as close as possible to the device V
CC
and V
BB
terminals.
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-
μ
F capacitors.
