Figure 3. EVM Board (Bottom Side)
Use the following when connecting and configuring the board for 48-kHz USB BTL mode:
1. Ensure the power supply is OFF. Connect the power supply positive terminal to J24 PVDD (red) and
negative to J1 GND (black).
2. Connect the left channel speaker or power resistor load (3–8 Ω) to the TAS3251EVM OUTA terminal
(J10 OUTA (red)) and the other side of the speaker or resistor load to the TPA3251EVM OUTB
terminal (J10 OUTB (black)).
3. Connect the right channel speaker or power resistor load (3–8 Ω) to the TAS3251EVM OUTA terminal
(J15 OUTA (red)) and the other side of the speaker or resistor load to the TPA3251EVM OUTB
terminal (J15 OUTB (black)).
4. Check to make sure that the power supply is connected to J24 only, and the speakers or resistor loads
are connected to J10 or J15 only, as their colors are the same.
5. Connect USB cable from the PC to the TAS3251EVM.
6. Ensure that DAC MUTE S1 and AMP RESET S3 are in the lower positions of MUTE and RESET.
7. Check Table 1 for all jumper and switch configurations.

1.3 Power Up
Ensure that the required connections and configurations have been checked. The TAS3251EVM board
can now be powered on.
1. Enable the power supply at 15 V to 36 V and ensure that D13 and D14 illuminates. LEDs D9 and D10
should not be illuminated.
2. Bring the DAC out of MUTE by switching DAC MUTE (S1) to NORMAL.
3. Bring the Power Stage out of RESET by switching AMP RESET (S3) to the high position. You should
see the FAULT LED (D10) blink once quickly, then remain unilluminated.
