This device includes a 2.5-V, 5-ppm/°C internal reference, eliminating the need for an external precision reference in most applications. A user-selectable gain configuration provides full-scale output voltages of 1.25 V (gain = ½), 2.5 V (gain = 1), or 5 V (gain = 2). This device operates from a single 2.7-V to 5.5-V supply, is specified monotonic, and provides high linearity of ±1 LSB INL. 1 • • • • • • • Performance – INL: ±1 LSB Maximum at 16-Bit Resolution – TUE: ±0.1% of FSR Maximum Integrated 2.5-V Precision Internal Reference – Initial Accuracy: 5 mV, Maximum – Low Drift: 5 ppm/°C, Typical High Drive Capability: 20 mA With 0.5 V From Supply Rails Flexible Output Configuration – User Selectable Gain: 2, 1 or ½ – Reset to Zero Scale or Midscale Wide Operating Range – Power Supply: 2.7 V to 5.5 V – Temperature: –40˚C to +125˚C 50-MHz, SPI-Compatible Serial Interface – 4-Wire Mode, 1.7-V to 5.5-V Operation – Daisy-Chain Operation – CRC Error Check Low Power: 0.7 mA/Channel at 5.5 V Small Package: 3-mm × 3-mm, 16-Pin WQFN Communication to the DAC80504 is performed through a 4-wire serial interface that operates at clock rates of up to 50 MHz. The VIO pin enables serial interface operation from 1.7 V to 5.5 V. The DAC80504 flexible interface enables operation with a wide range of industry-standard microprocessors and microcontrollers. The DAC80504 incorporates a power-on-reset circuit that powers up and maintains the DAC outputs at either zero scale or midscale until a valid code is written to the device. This device consumes low current of 0.7 mA/channel at 5.5 V, making it suitable for battery-operated equipment. A per-channel powerdown feature reduces the device current consumption to 15 µA. 2 Applications • • • • The DAC80504 is characterized for operation over the temperature range of –40°C to +125°C, and is available in a small, 3-mm × 3-mm, QFN package.

TI is not responsible or liable for such reproduced documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyers and others who are developing systems that incorporate TI products (collectively, “Designers”) understand and agree that Designers remain responsible for using their independent analysis, evaluation and judgment in designing their applications and that Designers have full and exclusive responsibility to assure the safety of Designers' applications and compliance of their applications (and of all TI products used in or for Designers’ applications) with all applicable regulations, laws and other applicable requirements. Designer represents that, with respect to their applications, Designer has all the necessary expertise to create and implement safeguards that (1) anticipate dangerous consequences of failures, (2) monitor failures and their consequences, and (3) lessen the likelihood of failures that might cause harm and take appropriate actions. Designer agrees that prior to using or distributing any applications that include TI products, Designer will thoroughly test such applications and the functionality of such TI products as used in such applications. TI’s provision of technical, application or other design advice, quality characterization, reliability data or other services or information, including, but not limited to, reference designs and materials relating to evaluation modules, (collectively, “TI Resources”) are intended to assist designers who are developing applications that incorporate TI products; by downloading, accessing or using TI Resources in any way, Designer (individually or, if Designer is acting on behalf of a company, Designer’s company) agrees to use any particular TI Resource solely for this purpose and subject to the terms of this Notice. TI’s provision of TI Resources does not expand or otherwise alter TI’s applicable published warranties or warranty disclaimers for TI products, and no additional obligations or liabilities arise from TI providing such TI Resources. TI reserves the right to make corrections, enhancements, improvements and other changes to its TI Resources. TI has not conducted any testing other than that specifically described in the published documentation for a particular TI Resource. Designer is authorized to use, copy and modify any individual TI Resource only in connection with the development of applications that include the TI product(s) identified in such TI Resource.

Unless TI has explicitly designated an individual product as meeting the requirements of a particular industry standard (e.g., ISO/TS 16949 and ISO 26262), TI is not responsible for any failure to meet such industry standard requirements. Where TI specifically promotes products as facilitating functional safety or as compliant with industry functional safety standards, such products are intended to help enable customers to design and create their own applications that meet applicable functional safety standards and requirements. Using products in an application does not by itself establish any safety features in the application. Designers must ensure compliance with safety-related requirements and standards applicable to their applications. Designer may not use any TI products in life-critical medical equipment unless authorized officers of the parties have executed a special contract specifically governing such use. Life-critical medical equipment is medical equipment where failure of such equipment would cause serious bodily injury or death (e.g., life support, pacemakers, defibrillators, heart pumps, neurostimulators, and implantables). Such equipment includes, without limitation, all medical devices identified by the U.S. Food and Drug Administration as Class III devices and equivalent classifications outside the U.S. TI may expressly designate certain products as completing a particular qualification (e.g., Q100, Military Grade, or Enhanced Product). Designers agree that it has the necessary expertise to select the product with the appropriate qualification designation for their applications and that proper product selection is at Designers’ own risk. Designers are solely responsible for compliance with all legal and regulatory requirements in connection with such selection. Designer will fully indemnify TI and its representatives against any damages, costs, losses, and/or liabilities arising out of Designer’s noncompliance with the terms and provisions of this Notice.
