1.2Basic Tools for Initial Board Power up

∙Up to 26V, 3A power supply (PVCC)

∙5V, 500mA power supply (VIN)

∙Banana cables for power supplies and speakers

∙Optical or coaxial cable for SPDIF interface based on signal source

∙Two 8Ω speakers (BTL) or 4Ω speakers (SE). Resistive loads can also be used

∙Optional: TAS5601EVM2 (for subwoofer connection when using BTL configuration)

2System Interfaces

This chapter describes the TAS5704EVM board in regards to power supply (PSU) and system interfaces.

2.1PSU Interface

The TAS5704EVM module is powered using two power supply sources a 10–26V (PVCC) power supply and a 5V (VIN) power supply. The 3.3V voltage levels are generated on the board using voltage regulators from VIN supply.

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

Maximum output stage supply voltage depends on the speaker load resistance. Check the recommended maximum supply voltage in the TAS5704 data sheet (SLOS563).
