PSU Interface (J150)

2.1 PSU Interface (J150)

The TAS5110D6DAD board must be powered from external power supplies. High-end audio performance requires a stabilized power supply with low ripple voltage and low output impedance.

Note:

The length of the power-supply cable must be minimized. Increasing the impedance of the PSU cable is equal to increasing the distortion for the amplifier at high output levels and low frequencies.

The maximum output stage supply voltage depends on the speaker load resistance. See the recommended maximum supply voltage in Chapter 4.
