TAS5411EVM User's Guide
The TAS5411-Q1 evaluation module (EVM) is intended to demonstrate the capabilities of the TAS5411-
Q1 device. All the device features can be accessed through the hardware and the software graphical user
interface (GUI) which is supplied. This user's guide contains a description of the EVM and the GUI. The
schematic, bill of materials (BOM), and board layout are included.
1 Hardware Overview
The TAS5411EVM showcases TI's TAS5411-Q1 analog input class-D closed-loop mono amplifier. The
EVM is usable as stand-alone platform with default I2C register settings. The EVM runs in default I2C
register settings. The EVM can also work with a USB2IIC-2 board and TAS5421-Q1 GUI for programming
the I2C register settings.

Hardware Overview www.ti.com
1.1 TAS5411EVM Features
• Runs without I2C initialization
• Has GUI control via USB port
• Passes EMC CISPR 25, class 5
1.2 TAS5411EVM Gain
The gain setting for TAS5411-Q1 device is I2C programmable. The four gain options are 20 dB, 26 dB, 32
dB, and 36 dB. Set the gain by modifying I2C control register 0x03. By default, the gain is 26 dB.
1.3 TAS5411EVM PWM Switching Frequencies
The PWM switching frequency is I2C programmable. The two f(SW) options are 400 kHz and 500 kHz.
Programming the frequency in control register 0x03 is via the GUI and IIC2USB-2 board. By default, f(SW)
is 400 kHz.
1.4 TAS5411EVM SpeakerGuard™ Protection Circuitry
The SpeakerGuard protection circuitry is programmable for different voltage levels. Programming the
levels in control register 0x03 via the GUI and IIC2USB-2 board. The control register shows the default
value for the SpeakerGuard protection-circuitry voltage level.

2 TAS5411EVM Setup
This section describes the TAS5411EVM setup and software installation.
Figure 2. TAS5411EVM Connection
Hardware requirements (see Figure 2):
• Computer running Windows XP, Windows 7, or Windows 8
• Power supply unit (PSU) 5–18 VDC
• USB cable (provided)
• PS2 cable (provided)
• USB2IIC-2 board (provided)
• Audio source: analog RCA input
Hardware setup:
1. Connect the 6-pin (PS2) cable to the TAS5411EVM on one end and to the USB2IIC-2 board on the
other (see Figure 2).
2. Plug in the USB cable from the PC to the USB2IIC-2 board (shown in Figure 3). The 3.3-V and USB
LINK LEDs light. The I2C LEDs (SDA/SCL) on the USB2IIC-2 board are blinking (colored boxes in
Figure 3).
3. Connect J2 (see Figure 2):
• PSU: Pin 7 (+) and Pin 6 (-) to PSU
• The speaker: Pin 5 (-) and Pin 4 (+) to speakers
• The audio input: Pin 2 (+) and Pin 1 (-) to input source
• Leave Pin 3 unconnected or connect it to ground.
4. Connect the PSU to the TAS5411EVM and turn on the power. The 3.3-V LED (D1 on the EVM board)
lights (see Figure 1).
5. Set switch S1 to OPERATION and S2 to UNMUTE (see Figure 1).
NOTE: The TAS5411EVM can run without a USB2IIC-2 board.

3 Software Installation
The TAS5411-Q1 use the TAS5421-Q1 GUI. It is available on the product folder by clicking on Tools and
Software tab to obtain the latest release of the GUI.
Execute the GUI installation program, TAS5421-Q1 GUI Setup.exe. After the program is installed, run the
TAS5421 EVM GUI. Figure 4 shows the start-up GUI image. The GUI displays the fault register when first
started. I2C data is polling by default. The I2C device address for the TAS5411-Q1 device is D8. Green
USB and I2C LEDs show that USB is connected and I2C communication is valid.

4 Using the GUI With the TAS5411EVM Board
The TAS5411EVM does not need initialization. On powering up, the device performs load diagnostics. If
there is no problem, the device transitions to play mode with the following default values are set:
• Gain: 26 dB
• f(SW): 400 kHz
• SpeakerGuard protection circuitry: Maximum voltage level
4.1 Checking the Fault Register
When the GUI first runs, the Register Detail box displays the fault register. The GUI runs with I2C data
polling as the default setting, clearing any previous faults after the first poll. If any fault condition is still
active after device goes into play mode, with the exception of open load, the device enters the load-
diagnostics mode.

4.4 Read and I2C Log
The I2C log displays I2C registers read data (see Figure 8). An option exists for reading the three registers
all at once or individually. Pressing the Read Faults button displays the fault register value on the I2C log
as well.
Starting the GUI enables the I2C log. An option is available to turn off logging on the pulldown I2C Log
menu.

4.5 I2C Polling
As mentioned above, the I2C polling is on when the GUI starts. To disable I2C polling, click on I2C polling
pulldown tab and unselect the check box. The polling time can also be changed as shown in Figure 9.
