The abbreviation EVM and the term evaluation module are synonymous with the DAC8562TEVM. 1.2 Introduction The DAC8562T is a 16-bit, low-power, buffered voltage-output, dual channel digital-to-analog converter (DAC) that operates from a single 2.7-V to 5.5-V supply. The DAC is controlled through a serial peripheral interface (SPI) that can operate at clock rates of up to 50 MHz. The EVM is designed to highlight the features and the performance of the 16-bit DAC. Additionally, the EVM includes a 2.5-V external reference voltage, resulting in an output range from 0 V to 2.5 V. The DAC8562TEVM is designed to give the user easy access to all pins on the DAC8562T. The evaluation module allows the user to control the DAC logic using onboard jumpers, or digitally through the J2 header. By default, the evaluation module is configured to be used with an onboard 2.5-V external reference, but can be easily modified to use the DAC internal reference by changing a jumper setting and enabling the internal reference using software. 1.3 Power and Motherboard Requirements This DAC8562TEVM board can be used as a standalone board or as a daughter card to the MMB0 Modular EVM motherboard. 1.3.1 Supply Voltage Ranges Table 1 lists the supply voltage ranges for the EVM. Table 1. Supply Voltage Ranges 1.3.2 Signal Range VDD +2.7 V to +5.5 V VREF_VIN +2.7 V to +15 V VREF_EXT 0 V to VDD Motherboard Supply Mode The MMB0 motherboard can supply the digital interface as well as the power supply voltage required by the DAC8562TEVM. This user’s guide focuses on the motherboard supply mode and its software. 1.3.3 Standalone Supply Mode The DAC8562TEVM can also be used without a motherboard, provided that the digital interface is driven by an external source. The supply voltage must be applied at TP1/VDD according to the specifications in Table 1. The MMB0 can still be used as a digital interface while using an external power supply. Remember to disconnect any shunt from JP1.

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.
