The AD5310R/AD5311R, members of the nanoDAC™ family, are low power, single-channel, 10-bit buffered voltage-out DACs. The devices include a 2.5 V, 2 ppm/°C internal reference. The output span can be programmed to be 0 V to VREF or 0 V to 2 ×VREF. All devices operate from a single 2.7 V to 5.5 V supply and are guaranteed monotonic by design. The devices are available in 10-lead MSOP packages.
The AD5310R/AD5311R also incorporate a power-on reset circuit that ensures that the DAC output powers up to zeroscale and remains there until a valid write takes place. The device contains a power-down feature that reduces the current consumption of the device to 2 μA at 5 V while in power-down mode.
The AD5310R/AD5311R use a versatile SPI or I2C interface, including an asynchronous RESET pin and a VLOGIC pin, allowing 1.8 V compatibility.

Product Lifecycle Recommended for New Designs
This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
Evaluation Kits (1)
The EVAL-AD5311RDBZ evaluation board is designed to quickly prototype AD5311R circuits and reduce design time. The evaluation board interfaces with the USB port of a PC via the SDP-B controller board. The AD5311R operates from a single 2.7 V to 5.5 V supply. Software can be downloaded via the EVAL-AD5311RDBZ product page that allows users to program the AD5311R.
This evaluation board requires the SDP-B controller board, which is available for order on the Analog Devices, Inc. website.
Full data on the AD5311R can be found in the AD5311R data sheet available from Analog Devices and should be consulted in conjunction with user guide UG-964 when using the evaluation board.

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.
