Figure 4. Connecting TAS5705EVM2 to MC57xxPSIA
The TAS5705EVM2 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 TAS5705 data sheet.
