TAS5720M Evaluation Board User's Guide Literature Number: SLOU437 December 2015 Chapter 1 SLOU437 – December 2015 Introduction To help the user investigate and evaluate the TAS5270M performance and capabilities, a fully populated evaluation board has been created. This board is shown in Figure 1-1. Connected to a PC, an external power supply (4.5 V ≤ PVDD ≤ 26.4 V) and a signal source, the TAS5270M Evaluation Board easily exercises the amplifier’s features. Figure 1-1.

Ensure all the jumpers are set correctly according to Table 2-1 and Figure 2-1. 2. Connect a speaker’s positive output terminal and negative output terminal respectively to OUTP (RED) and OUTN (BLACK) on the EVM board. Be careful not to mix up OUTP and PVDD terminals, since the colors are the same. The same applies to OUTN and GND terminals. 3. Connect a power supply (4.5 V-26.4 V) and ground reference respectively to PVDD (RED) and GND (BLACK) on the EVM board. 4. Connect a micro USB cable to EVM and PC to generate 3.3 V supply. 5. Go to Control Panel, Sound and select USB-AudioEVM under the Playback tab. Click on Set Default to make it the default playback device. Click on Properties and under the Advanced tab, make sure that the Default Format is shown as 2 channel, 16 bit, 48000 Hz (DVD Quality) in Figure 22 below. 6. Power on the power supply after checking that all the connections are correctly. 7. Load a music file in the Windows Media Player. Play that audio file and listen to the output. Table 2-1.

It is capable of delivering more than 15-W continuously into a 4-Ω speaker. The device has two address pins, which allow up to 8 I2C addressable devices to share a common TDM bus. The TAS5720M device SAIF supports a variety of standard stereo serial audio formats including I2S, Left Justified and Right Justified. It also supports a time division multiplexed (TDM) format that is capable of transporting up to 8 channels of audio data on a single bus. 6 General Description SLOU437 – December 2015 Submit Documentation Feedback Copyright © 2015, Texas Instruments Incorporated Chapter 4 SLOU437 – December 2015 Operating Conditions Table 4-1.

Each H-bridge has two PVDD input pins so that decoupling capacitors can be placed nearby. Use at least a 0.1-μF capacitor of X5R quality or better for each set of inputs. Keep the current circulating loops containing the supply decoupling capacitors, the H-bridges in the device and the connections to the speakers as tight as possible to reduce emissions. Use ground planes to provide the lowest impedance for power and signal current between the device and the decoupling capacitors. The area directly under the device should be treated as a central ground area for the device, and all device grounds must be connected directly to that area. Use a via pattern to connect the area directly under the device to the ground planes in copper layers below the surface. This connection helps to dissipate heat from the device. Avoid interrupting the ground plane with circular traces around the device. Interruption disconnects the copper and interrupt flow of heat and current. Radial copper traces are better to use if necessary.

Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
