Figure 4. Connecting TAS5708(TAS5710)EVM to MC57xxPSIA
The TAS5708(TAS5710)EVM is powered by two power supplies connected to the MC57xx controller
board: a 5-V power supply (VIN) and a 10-V to 26-V (PVCC) 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 TAS5708/10 (
