On the right side of the MC57xxPSIA is a terminal block and another on the left of the TAS5707/09EVM
(labeled J1). Carefully place the MC57xxPSIA block above the TAS5707/09EVM block and gently push
down.

Figure 4. Connecting TAS5707/09EVM to MC57xxPSIA
The TAS5707/09EVM is powered by two power supplies connected to the MC57xx controller board: a 5-V
power supply (VIN), and a 8-V to 24-V (PVDD) power supply. The 3.3-V level is generated on the board
by a voltage regulator from the 5-V supply.

Note:
The power-supply cable length must be minimized. Increasing the length of the PSU cable
increases the distortion of the amplifier at high output levels and low frequencies
increases the distortion of the amplifier at high output levels and low frequencies
The maximum output-stage supply voltage depends on the speaker load resistance. Check the
recommended maximum supply voltage in the TAS5707/09 data sheet.
