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. For a more-detailed description, read the complete user's guide. 1.1 Overview The EVM consists of a single printed circuit board (PCB) mounted inside a metal chassis for EMC testing and a power/speaker cable connector assembly. The EVM is different than the TAS5414B EVM as it does not need an I2C controller board to function. 1.2 Connections The connections are for an analog signal for the input, speaker loads, and power. The audio inputs are made through the four RCA connectors. The power connections and speaker connections are made using the 10-pin connector. The basic connections are: PVDD or power is connected to the EVM through the supplied 10-pin connector with the twisted red and black wires. The speakers or loads are also connected through the same 10-pin connector with the twisted red and white wires. See Figure 1for EVM input details. Figure 1.

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. This is the device automatically clearing the faults at startup. 2 EVM Description 2.1 Description of Inputs 2.1.1 Analog Inputs The TAS5424B EVM provides balanced input and the TAS5514B EVM provides unbalanced (singleended) inputs. The four RCA jacks on either EVM are provided for the audio input. The unbalanced inputs have the shield of the RCA connected to ground. The balanced inputs have the plus (+) input on the center pin of the RCA and the minus (–) input on the shield. The balanced ground can be connected to the chassis or Power– (GND). 2.1.2 Power The EVM requires one dc power connection. The connection is made through a 10-pin supplied connector. The black wire is ground and the red wire is connected to PVDD, which can range from 6 to 24 Vdc. 2.2 2.2.1 Description of Outputs Speaker and Power Connections The 10-pin connector on the EVM and the wiring harness provide the power connections and the speaker connections. The power connection consists of a pair of red and black twisted wires, which correspond to the plus (+) input and minus (–) input, respectively. This pair of wires must be attached to a power supply. The speaker connections consist of the remaining four pairs of red and white twisted wire. Each pair of red and white wires corresponds with a channel. The red wire corresponds to the plus (+) output, and the white wire corresponds to the minus (–) output. These wires must be terminated to a speaker load or resistive load.

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. The outputs can be paralleled by connecting the plus (+) of one channel to the plus (+) of the other channel. The minus (–) connection of one channel and the minus (–) connection of the other channel must be connected also. See the data sheet for more details on parallel outputs (PBTL). 2.3 2.3.1 Controls Standby The standby switch is located on the front panel. Having the toggle in the Standby ON position forces the TAS5514B into the standby mode. This is the same as a power-on reset (POR). POR shuts down the device. Setting the switch to the Standby OFF position puts the device in the EVM into the power up mode. The amplifier will perform load diagnostics and then will place the amplifier outputs into play mode. Please note, that any channel that has a shorted load, short to ground, or a short to power will not be placed into play mode. 6 TAS5514B Evaluation Module (EVM) User's Guide Copyright © 2012, Texas Instruments Incorporated SLOU345 – June 2012 Submit Documentation Feedback 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.
