The AD5680, a member of the nanoDAC family, is a single, 18-bit buffered voltage-out digital-to-analog converter (DAC) that operates from a single 4.5 V to 5.5 V supply and is 18-bit monotonic.
The AD5680 requires an external reference voltage to set the output range of the DAC. The part incorporates a power-on reset circuit that ensures the DAC output powers up to 0 V (AD5680-1) or to midscale (AD5680-2) and remains there until a valid write takes place.
The low power consumption of this part in normal operation makes it ideally suited to portable battery-operated equipment. The power consumption is 1.6 mW at 5 V.
The AD5680 on-chip precision output amplifier allows rail-to-rail output swing to be achieved. For remote sensing applications, the output amplifier’s inverting input is available to the user.
The AD5680 uses a versatile 3-wire serial interface that operates at clock rates up to 30 MHz, and is compatible with standard SPI®, QSPI™, MICROWIRE™, and DSP interface standards.
- Closed-loop process control
- Low bandwidth data acquisition systems
- Portable battery-powered instruments
- Gain and offset adjustment
- Precision setpoint control
Product Lifecycle Production
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
Evaluation Kits (1)
The EVAL-AD5680EBZ (Cypress based) is no longer available. Please use EVAL-AD5680DBZ (SDP based).
The EVAL-AD5680DBZ evaluation board is designed to help users quickly prototype new AD5680 circuits and reduce design time. The AD5680 operates from a single 4.5 V to 5.5 V supply.
For full specifications, see the AD5680 data sheet, which must be used in conjunction with user guide UG-989 when using the evaluation board.
The EVAL-AD5680DBZ evaluation board interfaces to the USB port of a PC via the SDP-B board. Software is available for download via the EVAL-AD5680DBZ product page that allows users to program the AD5680.

Tools & Simulations
Precision DAC Error Budget Tool
The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
