1.1.3 Connections and Board Configuration (BTL MODE)

Figure 1-16 shows the EVM board.

Use the following steps when connecting and configuring the board for BTL MODE:

  1. Ensure the power supply is OFF. Connect the power supply positive terminal to J1 PVDD (red) and negative terminal to J1 GND (black).
  2. Connect the left channel speaker, power resistor load (3–8 Ω) to the TPA3223EVM positive output terminal (J9 OUT1+ (red)) and other side of the speaker, power resistor to the TPA3223EVM negative output terminal (J9 OUT1– (black)).
  3. Connect the right channel speaker, power resistor load (3–8 Ω) to the TPA3223EVM positive output terminal (J2 OUT2+ (red)) and other side of the speaker, power resistor to the TPA3223EVM negative output terminal (J2 OUT2– (black)).
  4. Check to make sure that the power supply is connected to J1 only and speakers are connected to J9 or J2 only, as their colors are the same.
  5. Input Configuration:
    1. Differential Inputs: connect one differential XLR audio input to each DIFF IN1 (J14) and DIFF IN2 (J15). Install jumpers J10, J11, J20, and J21 to position 1:2 which is labeled as RCA or XLR. Jumpers J4 and J12 must be uninstalled for DIFF input.
    2. Single-Ended Inputs: connect one single-ended RCA audio input to IN1P (J3) and IN2P (J18). Install jumpers J10, J11, J20, and J21 to position 1:2 which is labeled as RCA or XLR. Jumpers J4 and J12 must be installed for SE input.
    3. Audio Interface Board Input: Install jumpers J10, J11, J20, and J21 to position 2:3 which is labeled as AIB. Jumpers J4 and J12 must be installed for SE input from the AIB or uninstalled for DIFF input from the AIB.
  6. Ensure that RESET S1 and MUTE S2 are in the lower positions of RESET and MUTE, respectively.
  7. Check Table 1-11 for all jumper and switch configurations
