The AD5689/AD5687 members of the nanoDAC+™ family are low power, dual, 16-/12-bit, buffered voltage output digital-to-analog converters (DACs). The devices include a gain select pin giving a full-scale output of 2.5 V (gain = 1) or 5 V (gain = 2). The AD5689/AD5687 operate from a single 2.7 V to 5.5 V supply, are guaranteed monotonic by design, and exhibit less than 0.1% FSR gain error and 1.5 mV offset error performance. Both devices are available in a 3 mm × 3 mm LFCSP and a TSSOP package.
The AD5689/AD5687 also incorporate a power-on reset circuit and a RSTSEL pin that ensures that the DAC outputs power up to zero scale or midscale and remain there until a valid write takes place. Each part contains a per channel power-down feature that reduces the current consumption of the device to 4 µA at 3 V while in power-down mode.
The AD5689/AD5687 uses a versatile serial peripheral interface that operates at clock rates up to 50 MHz. Both devices contain a VLOGIC pin that is intended for 1.8 V/3 V/5 V logic.

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.
The EVAL-AD5686RSDZ evaluation board is designed to help users quickly prototype new AD5686R circuits and reduce design time. The AD5686R operates from a single 2.7 V to 5.5 V supply. The AD5686R incorporates an internal 2.5 V reference to give an output voltage of 2.5 V or 5 V. The evaluation board also incorporates additional voltage references.
Full data on the AD5686R can be found in the data sheet, available from Analog Devices, which should be consulted in conjunction with the user guide when using the evaluation board.
The EVAL-AD5686RSDZ interfaces to the USB port of a PC via an SDP board. Software is supplied with the evaluation board to allow the user to program the AD5686R. A PMOD™ connection is also available for different microcontrollers.
This evaluation board is compatible with any Analog Devices SDP board, which can be purchased separately.
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.
