1 Introduction

This section provides an overview of the Texas Instruments (TI) TPA6013A4 evaluation module (EVM). The EVM user guide includes a brief description of the module and a list of EVM specifications.

1.1 Description

The TPA6013A4 is a stereo amplifier with 32-steps DC volume control. TPA6013A4 supports both speaker and headphone output. TPA6013A4 also has 2-to-1 stereo input MUX.
The TPA6013A4 EVM is a complete, stand-alone audio board. It contains the TPA6013A4 TSSOP (PWP) stereo amplifier. All components are Pb-free.

This section describes how to operate the TPA6013A4EVM.

2.1 Quick-Start List for Stand-Alone Operation

Use the following steps when operating the TPA6013A4EVM stand-alone board or when connecting the EVM into an existing circuit.
2.1.1 Power and Ground
1. Ensure that the external power sources are set to OFF.
2. Set the power supply voltage between 4 V and 5.5 V. When connecting the power supply to the EVM, first connect the ground connection to GND at the POWER terminal block, and then connect the positive supply to VDDat the POWER terminal block. Verify that the connections are made to the correct terminals.
2.1.2 Inputs and Outputs
2.1.2.1 Audio Input
1. Connect audio source at the RCA jacks LLINEIN and RLINEIN. Shunt jumper RIN and LIN for single-ended input.
2. Short position 2 and 3 at 3-pin header RH JP. Audio source right channel will go into RLINEIN of the amplifier.
3. Short position 2 and 3 at 3-pin header LH JP. Audio source left channel will go into LLINEIN of the amplifier.
4. TPA6013A4 has 2-to-1 input MUX that can accept 2 single-ended stereo source. To use the MUX: (a) Connect the first audio source at RCA jacks LLINEIN and RLINEIN. Shunt jumper RIN and LIN for
single-ended input. (b) Connect the second audio source at test points RHPIN and LHPIN. (c) Remove shunts at 3-pin headers RH JP and LH JP. (d) To select LLINEIN and RLINEIN, remove shunt at HP/LINE. (e) To select LHPIN and RHPIN, shunt at HP/LINE.

2.1.2.2 Audio Output
1. Connect speakers at terminal blocks ROUT and LOUT.
2. TPA6013A4 supports both speaker and headphone output. To select speaker output, remove headphone in the headphone jack. To select headphone output, insert headphone into the headphone jack; speaker amplifiers will be turned off automatically.
2.1.2.3 Other Controls
1. Shutdown is controlled by pushbutton S1. Press and hold S1 to place the TPA6013A4 in shutdown mode. Release S1 to reactivate the TPA6013A4.
2. Volume is controlled by potentiometer.
3. Shunt FADE to enable fade function. Remove shunt to disable fade function.
4. To use SEDIFF and SEMAX function, apply voltage at test points SEDIFF and SEMAX. SEDIFF and SEMAX can also be controlled by placing resistors of different values at R4 and R7.
