Using The TPA122 MSOP EVM With the Plug-N-Play Evaluation Platform
3-9
Details
3.3.4 Power Requirements
The TPA122 MSOP Audio Power Amplifier Evaluation Module can operate
from a V
DD
voltage between approximately 2.5 V and 5.5 V.
The TI Plug-N-Play Audio Amplifier Evaluation Platform with a voltage
regulator EVM installed on it can provide a regulated 3.3-V or 5-V V
DD
supply
from a wide variety of unregulated V
CC
voltage inputs between approximately
5.5 V and 12 V, including an onboard 9-V battery. Or, an external regulated
power source can be used to supply V
DD
voltage to the platform and the
TPA122 evaluation module installed on it.
The platform is equipped with overvoltage and reverse-polarity supply voltage
input protection in the form of fused crowbar circuits.
V
DD
voltage applied to platform screw terminals J6
MUST NOT
exceed
the absolute maximum rating for the TPA122 amplifier IC installed on the
evaluation module (5.5 V), or damage to the IC may result. In no case
should V
DD
voltage of the incorrect polarity or in excess of 6.1 V be applied
to screw terminals J6 of the platform, or the power protection circuit on the
V
DD
line will trip.
V
CC
voltage applied to the platform
MUST NOT
exceed the maximum
voltage input specified for the voltage regulator module installed in socket
U6 (12 V for the SLVP097), or damage to the voltage regulator module
may result. In no case should V
CC
voltage applied to the platform exceed
15 V, or the overvoltage protection circuit on the V
CC
bus will trip.
