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 ensure 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.

AD5686R Evaluation Board

Features and Benefits

  • Full featured evaluation board for the AD5686R
  • On-board references
  • Various link options
  • PC control in conjunction with the Analog Devices, Inc., System Demonstration Platform (SDP)

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.
