The AD5694, a member of the nanoDAC+™ family, is a low power, quad, 16-bit buffered voltage output DAC. The device includes a gain select pin giving a full-scale output of 0V to VREF (gain = 1) or 0V to 2.VREF (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 1.5 mV offset error performance. The device is available in a 3 mm × 3 mm LFCSP package and in a TSSOP package.

The AD5696 incorporates a power-on reset circuit and a RSTSEL pin; the RSTSEL pin ensures that the DAC outputs power up to zero scale or midscale and remain at that level until a valid write takes place. The part contains a per-channel power-down feature that reduces the current consumption of the device in power-down mode to 4 µA at 3 V.

The AD5696 uses a versatile 2-wire serial interface that operates at clock rates up to 400 kHz and includes a VLOGIC pin intended for 1.8 V/3 V/5 V logic.

EVAL-AD5696RARDZ

Evaluation Board for AD5696R (I2C, TSSOP)

Evaluation Board for AD5696R (I2C, TSSOP)

Features and Benefits

  • Full featured evaluation boards for the AD5696R (I2C, 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.

Product Detail

The EVAL-AD5696RSDZ evaluation board is designed to help users quickly prototype AD5696R circuits and reduce design time. The AD5696R operates from a single 2.7 V to 5.5 V supply. The AD5696R incorporates an internal 2.5 V reference to give an output voltage of 2.5 V or 5 V. The EVAL-AD5696RSDZ evaluation board also incorporates additional voltage references.


The EVAL-AD5696RSDZ 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-AD5696RSDZ product page to use with the evaluation board to allow the user to program the AD5696R. 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-AD5696RSDZ evaluation board is compatible with any Analog Devices SDP board, which can be purchased separately.


For full details, see the AD5696R data sheet, which must be used in conjunction with UG-726 when using the EVAL-AD5696RSDZ evaluation board.
