Connections to the EVM power supply and output connectors can be made by inserting stripped wire or using banana jacks. The input connectors are RCA phono jacks. 2.1.1 Power Supply A single power supply is required to power the EVM. Because most of the pins are PVCC compliant, the PVCC supply can also be used to power the analog supply (AVcc) and to pull up the logic pins for shutdown (SD) control, and gain (GAIN). PLIMIT can be powered by an external supply connected to the PLIMIT pin. Do not power the PLIMIT pin through the PLIMIT network when the PVCC supply is turned off. This can damage the IC. Table 1. Power Supply Requirements Description Voltage Range Current Requirements Wire Size PVCC 4.5 V to 26 V 3A 24 AWG 1. Ensure that the external regulated power supply is turned OFF. 2. Connect the external regulated power supply, adjusted from 4.5 V to 26 V, to the PVCC and GND banana jacks on the EVM taking care to observe marked polarity. 2.1.2 EVM Preparations Inputs and Outputs 1. For a BTL configuration, remove jumpers from JP5 and JP6 and connect loads across the outputs (LEFT+ and LEFT–) and (RIGHT+ and RIGHT–). For PBTL configuration, insert jumpers on JP5 and JP6 and connect a single load from one of the left speaker jacks to one of the right speaker jacks. 2. Connect audio inputs, either differential or single-ended, to the LIN and RIN RCA phono plugs for BTL operation. For PBTL operation, connect a single input, differential or single-ended, to the RIN RCA phono plug. Table 2.

Verify correct power supply voltage and polarity, and turn the external power supply ON. The EVM begins to operate. 2. Adjust the audio source for the correct volume.

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.
