User's Guide SLOU345 – June 2012 TAS5514B Evaluation Module (EVM) User's Guide The TAS5514B evaluation module (EVM) is intended to be used to demonstrate the capabilities of the device. All the device features can be accessed through the hardware supplied. This user’s guide contains a description of the EVM. Included are the EVM schematics, bill of materials, and the board layout. 1 Quick-Start Guide This section provides a guide to set up and power up the EVM without the details of its operation.
EVM Description www.ti.com 1.3 Initial Power Up Before applying power, check to make sure the standby control switch is in the Standby OFF position, as shown in Figure 2. Figure 2. Front Panel Labels Apply power: the Standby, Mute, and Power LEDs should be on. This indicates that the unit is powered, and the TAS5514B is in Standby Mode. The TAS5514B is place into play mode by simply moving the toggle switch to the Standby OFF position. The Fault LED may flash once and then go off.
EVM Description www.ti.com See Figure 1for more details on the 10-pin connector on the EVM, Figure 3for more details about the speaker cables, and Figure 4for the power and speaker-cables connections to the EVM. Figure 3. Wiring Harness for Power and Speaker Connections Ch. 4 Ch. 3 Ch. 2 Ch. 1 Power Figure 4. Power and Speaker Connections to the EVM NOTE: Do not connect any of the speaker outputs to ground. The TAS5514B has full bridged outputs; connecting to ground triggers a fault.
TAS5514B EVM Schematic www.ti.com 2.4 Indicator Description There are five LED indicators on the chassis next to the standby switch. The LED farthest away from the standby switch is for the 3.3 Vdc supply. The 3.3 V supply is needed for the LEDs and the standby circuit. The other four LEDs output pins: FAULT, CLIP_OTW, STANDBY, and MUTE. In normal play mode, these four LEDs should not light. 3 TAS5514B EVM Schematic The schematic for the TAS5514BDKD EVM is shown on the following pages.
