The AD5686/AD5684, a member of the nanoDAC+™ family, is a low power, quad, 16-/12-bit buffered voltage output DAC. The device includes a gain select pin giving a full-scale output of 2.5 V (gain = 1) or 5 V (gain = 2). All devices operate 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 devices are available in a 3 mm × 3 mm LFCSP and a TSSOP package.

The AD5686/AD5684 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 at that level 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 AD5686/AD5684 employ a versatile SPI interface that operates at clock rates up to 50 MHz, and all devices contain a VLOGIC pin 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.

Product Detail

This Evaluation Board is no longer available for ordering. Please see the AD5686R Evaluation Board.


The Evaluation board for the AD5684R contains a SDP-B connection and software allowing the AD5684R to be controlled from a SDP-B board.


The SDP Controller board is a separate list item in the ordering guide below (EVAL-SDP-CB1Z). If you have not previously purchased an SDP Controller board, please do so to ensure a full evaluation setup.
