Key Parameters Key Parameters Power Supply Voltage 8 to 26 Volts Number of Channels 2 Bridge Tied Load (BTL) Stereo Load Impedance Stereo BTL 4 to 8 (connect 33-mH series inductor for 4 or 68-mH inductor for 8 if using the ferrite bead filters) Load Impedance Mono PBTL 2 to 8 (connect series inductors if using with ferrite bead filters) Output Power BTL 15 W per channel Output Power PBTL 30 W 2 Operation 2.1 Quick Start List for Stand-Alone Operation Follow these steps to use the TPA3110D2 EVM stand-alone or when connecting it into existing circuits or equipment. Connections to the EVM module can be made by inserting stripped wire or banana plugs for the power supply and output connections. The input connectors are RCA phono jacks. SLOU263A - July 2009 - Revised July 2010 TPA3110D2 EVM Audio Amplifier Evaluation Board Copyright (c) 2009-2010, Texas Instruments Incorporated 3 Operation www.ti.com Power Supply A single power supply is required to power up the EVM. Since most of the pins are PVCC compliant, the PVCC supply can also be used to power the analog supply (AVCC) and can be used to pull up the logic pins for shutdown (SD) control, fault detection (FAULT), gain (GAIN0 and GAIN1), and PBTL as long as the voltage slew rate is limited to 10 V/ms. GVDD is an internally generated supply for the output FETs and is also used to power the PLIMIT voltage divider circuit on the EVM. PLIMIT is GVDD compliant, but not PVCC compliant. PLIMIT can also be powered by an external supply connected to the PLIMIT pin. Take care not to power the PLIMIT pin (or connect power to the GVDD pin inadvertently through the PLIMIT network) when the PVCC supply is turned off. This can cause damage to the IC. Table 2. Power Supply Requirements Description Voltage Range Current Requirements Minimum Wire Size PVCC 8 to 26 V 3A 24 AWG Evaluation Module Preparations 1. Ensure that the external power source is set to OFF. 2. Connect the external regulated power supply adjusted from 8V to 26V to the module PVCC and GND banana jacks taking care to observe marked polarity. Inputs and Outputs 1. For a BTL Configuration, connect a Load(s) across the outputs (LEFT+ and LEFT-) and (RIGHT+ and RIGHT-). For PBTL configuration, connect a single load from one of the left speaker jacks to one of the right speaker jacks depending on how the filters are loaded. 2. Connect audio inputs, either differential or single-ended, to the LIN and RIN RCA phono plugs for BTL operation. For PBTL operation, apply a single input, differential or single-ended, to the RIN RCA phono plug. Control Inputs 1. Ensure the mode jumpers, PBTL, GAIN0, GAIN1, are set correctly depending on the desired operating state. Also, make sure to connect the left outputs together and the right outputs together at the LEFT and RIGHT molex connectors if PBTL operation is desired. Power Up 1. Verify correct voltage and input polarity and turn the external power supplies ON The EVM should begin operation. 2. Adjust the audio source for the correct volume and enjoy! Table 3.

TPA3110D2 Control Guide (continued) Control Function Options PBTL Sets the amplifier in PBTL mode Insert jumper to defeat PBTL If PBTL jumper is removed (PBTL mode), the Left mode and run in normal outputs (OUTPL and OUTNL) as well as the Right stereo BTL mode. outputs (OUTPR and OUTNR) are synchronized and in phase. This allows them to be connected together before the reconstruction filter for PBTL operations. For PBTL operation, connect the OUTPL and OUTNL to each other and connect the OUTPR and OUTNR to each other. This can be done by shorting the two pins of the molex connectors labeled LEFT and RIGHT. JP3, JP4, JP5, Connects LC filters to outputs. and JP6 SLOU263A - July 2009 - Revised July 2010 Notes The LC filters are not installed in this version of the EVM. However, the inductors are shipped with the EVM package. They can be installed and used as normal reconstruction filters or to smooth the audio waveforms for measurement. They can also be used when driving resistive loads to simulate a speaker load. This EVM is meant to demonstrate filter-free operation with just a ferrite bead and small capacitor for good EMI performance.

FCC Warning This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR EVALUATION PURPOSES ONLY and is not considered by TI to be a finished end-product fit for general consumer use. It generates, uses, and can radiate radio frequency energy and has not been tested for compliance with the limits of computing devices pursuant to part 15 of FCC rules, which are designed to provide reasonable protection against radio frequency interference. Operation of this equipment in other environments may cause interference with radio communications, in which case the user at his own expense will be required to take whatever measures may be required to correct this interference. EVM Warnings and Restrictions It is important to operate this EVM within the input voltage range of -0.3 V to 6.3 V and the output voltage range of -0.3 V to 30 V . Exceeding the specified input range may cause unexpected operation and/or irreversible damage to the EVM. If there are questions concerning the input range, please contact a TI field representative prior to connecting the input power. Applying loads outside of the specified output range may result in unintended operation and/or possible permanent damage to the EVM. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load specification, please contact a TI field representative. During normal operation, some circuit components may have case temperatures greater than 85 C. The EVM is designed to operate properly with certain components above 85 C as long as the input and output ranges are maintained. These components include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of devices can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during operation, please be aware that these devices may be very warm to the touch.
