The AD5685R nanoDAC+™ is a quad, 14-bit, rail-to-rail, voltage output DAC. The device includes a 2.5V, 2ppm/˚C internal reference (enabled by default) and a gain select pin giving a full-scale output of 2.5V (gain=1) or 5V (gain=2).
The device operates from a single 2.7 V to 5.5 V supply, is guaranteed monotonic by design and exhibits less than 0.1% FSR gain error and 1.5mV offset error performance. The device is available in a 3mm X 3mm LFCSP and a TSSOP package.
The AD5685R also incorporates a power-on-reset circuit and a RSTSEL pin that ensures the DAC outputs power up to zero-scale or midscale, and remain there until a valid write takes place. Each device contains a per-channel power-down feature that reduces the current consumption of the device to 4 uA at 3 V while in power-down mode.
The AD5685R employs a versatile SPI interface that operates at clock rates up to 50 MHz and includes a VLOGIC pin intended for 1.8V/3V/5V logic.

EVAL-AD5686R
AD5686R Evaluation Board
Product Detail
The EVAL-AD5686RSDZ evaluation board is designed to help users quickly prototype 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.
The EVAL-AD5686RSDZ evaluation board interfaces to the USB port of a PC via a system demonstration platform (SDP) board. The analysis control evaluation (ACE) software is available for download from the EVAL-AD5686RSDZ product page to use with the evaluation board to allow the user to program the AD5686R. A PMOD connection is also available to allow the connection of microcontrollers to the evaluation board without the SDP board. Note that when a microcontroller is used through the PMOD connection, the SDP board must be disconnected, and the user is unable to operate the ACE software.
The EVAL-AD5686RSDZ evaluation board is compatible with any Analog Devices SDP board, which can be purchased separately.
For full details, see the AD5686R data sheet, which must be consulted in conjunction with user guide (UG-725) when using the evaluation board.

EVAL-AD5686RARDZ
Evaluation Board for AD5686R (SPI, TSSOP)
Features and Benefits
- Full featured evaluation boards for the AD5686R (SPI, TSSOP)
- On-board references
- Various link options
- PC control in conjunction with the Analog Devices, Inc., EVALSDP-CK1Z (SDP-K1 controller board
Product Detail
This user guide details the operation of the EVAL-AD5686RARDZ (serial peripheral interface (SPI)) evaluation board and the EVALAD5696RARDZ (I2C) evaluation board for the AD5686R (SPI) and the AD5696R (I2C), respectively, which are both quad-channel, voltage output digital-to-analog converters (DACs).
The EVAL-AD5686RARDZ and the EVAL-AD5696RARDZ are designed to facilitate quick prototyping of the AD5686R circuit and the AD5696R circuit, respectively, thereby reducing design time. Both devices operate from a single 2.7 V to 5.5 V supply. Additionally, these devices also incorporate an internal 2.5 V reference. However, if required, a different reference voltage can be applied via the EXT_REF SMB connector. Although these two DACs share common features, they differ in their digital interface protocols. The AD5686R uses SPI whereas the AD5696R uses I2C.
The EVAL-AD5686RARDZ and the EVAL-AD5696RARDZ interface with the USB port of a PC via a system demonstration platform (SDP) controller board. The analysis, control, evaluation (ACE) software is available for download from both the EVAL-AD5686RARDZ product page and the EVAL-AD5696RARDZ product page. The ACE software can be used with the EVAL-AD5686RARDZ or the EVAL-AD5696RARDZ to allow the user to program the AD5686R and the AD5696R, respectively. A PMOD connection can also be found on the evaluation board to allow the connection of microcontrollers without the SDP controller board. Note that when a microcontroller is used through the PMOD connection, the SDP controller board must be disconnected. Therefore, the user cannot use the ACE software.
The EVAL-AD5686RARDZ and the EVAL-AD5696RARDZ both require the EVAL-SDP-CK1Z (SDP-K1) controller board, which is available for purchase from Analog Devices.
For full details, see the AD5686R data sheet or the AD5696R data sheet, which must be consulted in conjunction with this user guide when using either the EVAL-AD5686RARDZ or the EVALAD5696RARDZ.
