2.1.1
Connecting the TAS5711EVM to MC57xxPSIA
On the right side of the MC57xxPSIA is a terminal block and another is located on the left of the
TAS5711EVM (labeled J1). Carefully place the MC57xxPSIA block above the TAS5711EVM block and
gently push down.

PSU Interface
The TAS5711EVM is powered by two power supplies connected to the MC57xx controller board: a 5-V
power supply (VIN), and a 8-V to 26-V (PVDD) power supply. The 3.3-V level is generated on the board
by a voltage regulator from the 5-V supply.

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
