The TAS5602EVM2 evaluation module consists of a single class-D stereo audio power amplifier completewith a small number of external components mounted on a circuit board that can be used to directly drivespeakers using a TAS3308 EVM as the input. The input connector for the TAS5602EVM2 is configured toconnect directly to the TAS3308 EVM PWM connector. The TAS5602EVM2 can be configured to drive 2stereo BTL channels up to 20W/ch or 4 SE (single-ended) channels up to 10/ch. It is also possible toconfigure the EVM to drive speakers in a 2.1 configuration with 2 channels of SE stereo and one channelof BTL subwoofer. The user can also connect to the TAS5602EVM2 input with a ribbon cable from atarget system if desired.
This document assumes that the user has obtained a TAS3308 EVM and has set up the PurePathStudio™ software on a test computer with USB interface. The Quick Setup Guide in the TAS3308 EVMUser's Guide (TI document SLEU093 ) describes a method to get the TAS3308 EVM up and runningefficiently.
The TAS3308 EVM outputs 6 PWM channels plus a VALID/SYNC signal. The six PWM channels aregrouped into three stereo channels named PWM1 L and R, PWM2 L and R, and PWM3 L and R. TheTAS5602EVM2 is configured to connect to PWM3, which consists of 4 output lines

Operation www.ti.com
Follow these steps to use the TAS5602EVM2 along with the TAS3308 EVM. Power and speakerconnections to the EVM module can be made by inserting stripped wire or using banana plugs for thepower supply and output connections. The inputs can be connected directly to the TAS3308 EVM via the2×20 pin header. Set up the TAS3308 according to the instructions given in the TAS3308EVM User'sGuide (SLEU093 ). Download the TAS5602 configuration file from the TAS5602 product folder. This can beused to optimize the TAS3308 set-up for the TAS5602 power stage.
Some additional adjustments to the Pure Path Studio™ setup for TAS3308 may be necessary to run theTAS5602EVM2.
1. The input selection is performed by selecting the StereoMux and changing the Mux Select Property toStereoCh1 or StereoCh2 depending on the type of signal being used. Select StereoCh1(TAS3308ADCIn-1) if it is Analog input; select StereoCh2 (TAS3308SAPIn-1) if it is SPDIF formatdigital input.2. Build the process flow above and select Build/Generate Code3. Select Build/Download, and then Run.4. Press the Mute button on the TAS3308 EVM to turn it to the OFF state. The MUTE indicator LEDshould turn off. This is necessary since the TAS3308 EVM transitions to the run mode with the MUTEin the ON state.

Place the TAS3308 EVM and TAS5602EVM2 at the same height and let the 40 pin connector on eachboard face each other. Push them together carefully until they make a solid connection
Figure 2. TAS3308EVM/ TAS5602EVM2 External Connections
1. Three power supplies are required: two 9V, 1.7A power supplies for the TAS3308 EVM and one 10V -26V, 4A supply for the TAS5602EVM2.2. Ensure that all external power sources are set to OFF.3. Connect the two 9V supplies to the TAS33088 EVM. Connect the power supply adjusted from10V–26V to the module TAS5602 PVCC and GND banana jacks taking care to observe markedpolarity.
Speaker Connections (BTL Configuration)1. Connect a speaker across OUTA ( J2) and OUTB ( J4). Connect another speaker across OUTC ( J6)and OUTD ( J8)2. Install Jumpers 1-5.
Speaker Connections (SE Configuration)1. Connect a speaker across the following pairs of jacks: OUTA ( J2) and GND ( J3), OUTB ( J4) and GND(J5) , OUTC ( J6) and GND ( J7), and OUTD ( J8) and GND ( J9).2. Remove Jumpers 1-5.

2.5 Power Up
Operation www.ti.com
Control Inputs1. HIZ: This terminal is active LOW. This terminal can be used to ( < 1ms) disable the output switching inthe event of a power failure. If the HIZ is tied to RESET, the volume ramps up slowly at start-up, butthe output switching is stopped at power down. Place JP6 in the NORM position to bypass thefunction. This position ties HIZ to the 3.3 V supply. Place JP6 in the RESET position to tie HIZ toRESET. Place JP6 in the EXT position if manual test is desired. When JP6 is in the EXT position, theHIZ pin is accessible via the test point "EXT" and the HIZ function can be exercised by grounding thistest point to the board ground. The PGND at the power supply ground can be used for this test.2. RESET: This terminal is active LOW. This terminal can be used for pop-free start/stop.3. FAULT: This terminal is active LOW. This terminal is used to indicate short circuit faults. If this pin islow, a short circuit at the output has been detected. FAULT will be reset if the RESET pin is pulled low,or the PVCC supplies are turned off. Thermal fault is not reported on this pin.4. THERM_WARN: This terminal is a TTL compatible push-pull output. Thermal warning flag goes low ifthe die temperature has reached 125 °C. This pin is automatically reset if the temperature drops backbelow 105 °C. The THERMAL WARNING LED lights when this pin goes low.5. SE/ BTL: This pin controls the starting up timing based on the output configuration. If SE/ BTL isconnect to DVDD (SE), the start-up is slow to allow a pop-free start-up in single-ended configurations.If the SE/ BTL is connect to GND, the start-up is faster, as desired, for BTL configurations. Use thejumper, JP1, to set this function.
1. Verify correct voltage and input polarity for the ±9V supplies for the TAS3308 EVM and 10V - 26Vsupply for the TAS5602EVM2. Turn the TAS3308 power supplies ON.2. Prepare the TAS3308 EVM for audio play by using the Quick Setup Guide in the TAS3308EVM User'sGuide (TI document SLEU093). The user may want to turn down the volume on the audio source priorto enabling the audio outputs to the TAS5602 audio amplifier. Connect the audio source to theTAS3308 EVM and use the Pure Path Studio GDE to select the correct Mux to route the audio signalto the PWM3 output.3. Turn on the power supply for the TAS5602EVM2. LED2 next to the PVCC jack on the TAS5602EVM2should be lit. Audio power should be reaching the speakers (loads) at this time.4. Adjust the audio level using the Pure Path Studio GDE to produce the required audio signal.

EVM WARNINGS AND RESTRICTIONS
It is important to operate this EVM within the input voltage range of 0V to 5V and the output voltage range of 0V to 26V.Exceeding the specified input range may cause unexpected operation and/or irreversible damage to the EVM. If there are questionsconcerning 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 operateproperly with certain components above 85 °C as long as the input and output ranges are maintained. These components include but arenot limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of devices can be identifiedusing 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.
