Using The TPA112 MSOP EVM With the Plug-N-Play Evaluation Platform
3-8
Details
3.3.3 Power Requirements
The TPA112 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 TPA112
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 TPA112 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.
