Hardware Description
Power Requirements
The SCI-TPA2038-MVK utilizes either the 5.5VDC from the Pro Motherboard or an external 2.5 to 5.5V DC power source.
If the Pro Motherboard power rail is utilized by itself, the maximum current draw from the 5.5V rail is limited to 200ma.
If an external source is utilized, a 5.5V, 2A DC power supply is recommended. The maximum short circuit current for each TPA2038D1 is 2Amps @ 3.6 Volts.
The SCI-TPA2038-MVK module is supported by the MAVRK AppMonitor and AppSelect tools. For more information on these tools and how to install them, refer to the How to get the MAVRK Software link below.
The preferred method for working with this EVM is through the use of the MAVRK Pro Motherboard.
The motherboard will provide the digital control for this EVM. Power can be supplied by the Pro Motherboard or an external 5V, 2A DC supply. The software demo uses MAVRK_SCI4 as the image in Figure 4 shows, however (with a small change in software) it is also possible to insert the SCI-TPA2038-MVK into any of the other 3 SCI slots are retain full functionally. Also in the picture is the AFE-BREAKOUT-MVK in MAVRK_AFE4 which provides pass through of the digital signals to the SCI-TPA2038-MVK.
The power source for the Pro Motherboard in this demo shown in Figure 4 is the USB cable. It should be noted that when any board on the MAVRK board is installed or removed, all power sources should be moved first by pressing the Standby button and the SCI-DRV8814-MVK power source MUST be off as well to prevent possible damage to the boards.
Typical installation of the module is as follows:
1. Plug in the USB.
a. The Standby button should be blue, which effectively removes all power from the modules on the mother board.
2. Run the MAVRK AppSelect tool
3. Install all modules required for the demo
a. An MCU module to initialize the motherboard and to communicate to the SCI-DRV8814-MVK.
b. At least one AFE-BREAKOUT-MVK module. It should be noted multiple AFE's can be installed.
c. At least one SCI-TPA2038-MVK module in the slot below the AFE Breakout module.
3. Install one of the Filter or Passthrough modules in the output filter stage of the TPA2038.
4. Install the JTAG debugger if a C Compiler is used to download code into the MCU. Otherwise the QT tool will use the USB connection to download the code.
5. Press the Standby button to provide power to the motherboard modules.
6. Activate power source to the SCI-DRV8814-MVK.

EVM Connectors, Fuses, and Switches
The SCI-TPA2038-MVK has two common modes for operation, a stand-alone mode, where one of the analog input jacks is tied to the input of the TPA2038 and a second mode where an Audio Codec is used in the AFE slot to route audio to the TPA2038.
Stand Alone Mode
Figure 5 shows the Stand Alone mode. Left and Right analog speakers are connected in the P1 SPKR_OUT screw terminal.
Jumper JP03 IN SEL will need to be removed to re-route the audio from IN1 Audio Jack J1.
Figure 5. Standalone Mode for the SCI-TPA2038-MVK
Audio Codec Mode
Figure 6 shows the installation of JP03 IN SEL to disable the routing of the Audio from J1 IN1 to the TPA2038.
In this mode, J1 IN1 and J2 IN2, shown in Figure 6, and J3 HPOUT shown in Figure 7 are routed to the AFE Slot above the SCI-TPA2038-MVK.
The input of the TPA2038 Amplifiers are also tied to the AFE Slot above the SCI--TPA2038-MVK.

EVM Test Points
Several test points exist on the SCI-TPA2038-MVK.
The figure below shows two ground test points. These test points can be used to ground scope or volt meter probes.
The AVDD_5.5V test point can be used to monitor the supply into the SCI-TPA2038-MVK.
There are also two test points for the Left and Right channel. These test points can be used to view the signals going into the TPA2038's.
Figure 11. Ground Test Points for the SCI-TPA2038-MVK
EVM LEDs
The figure below shows the only LED on the TPA2038. This LED, signalling an over current condition, is red and during normal operation is not lit (off). If the Over Current LED is lit, the 200ma barrier has been reached on the Pro Motherboard's supply voltage of 5.5V. If this LED remains lit, the best solution is to drop the gain of the TPA2038 or power the SCI-TPA2038-MVK with an external 5V DC power supply.
