Installation
The following sections describe the TAS5707/09EVM board in regards to power supply (PSU) and system
interfaces.
2.1.1
Connecting the TAS5707/09EVM to MC57xxPSIA
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.

2.1.2
PSU Interface
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
The maximum output-stage supply voltage depends on the speaker load resistance. Check the
recommended maximum supply voltage in the TAS5707/09 data sheet.
