Precision DAC Error Budget Tool

The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.

Features and Benefits

  • Full featured evaluation board for the AD5675R (I2C)
  • Various link options
  • PC control in conjunction with the Analog Devices, Inc., EVALSDP-CK1Z (SDP-K1) controller board

Product Details

The user guide details the operation of the EVAL-AD5675RARDZ (I2C) evaluation board and the EVAL-AD5676R2ARDZ (serial peripheral interface (SPI)) evaluation board for the AD5675R (TSSOP, I2C) and AD5676R (TSSOP, SPI), respectively, which are both octal channel, voltage output digital-to-analog converters (DACs).

The EVAL-AD5675RARDZ and the EVAL-AD5676R2ARDZ evaluation boards are designed to facilitate quick prototyping of the AD5675R or AD5676R circuits, thereby reducing design time. Both devices operate from a single 2.7 V to 5.5 V supply. Additionally, these devices both have an internal 2.5 V reference. A different reference voltage (VREF) can be applied via the EXT_REF SMB connector, if required. While sharing common features, the two DACs differ in their digital interface protocols. The AD5676R employs SPI, while the AD5675R employs I2C.

The EVAL-AD5675RARDZ and the EVAL-AD5676R2ARDZ evaluation boards interface to the USB port of a PC via a System Demonstration Platform (SDP) controller board (EVAL-SDP-CK1Z (SDP-K1)). The Analysis | Control | Evaluation (ACE) software is available for download from both the EVAL-AD5675RARDZ product page and the EVAL-AD5676R2ARDZ product page. This software can be used with the evaluation board to allow the user to program the AD5675R and AD5676R, respectively. A PMOD connection is also available to allow the connection of microcontrollers to either evaluation board. Note that when a microcontroller is used through the PMOD connection, the EVAL-SDP-CK1Z (SDP-K1) must be disconnected, and the user cannot use the ACE software.

The EVAL-AD5675RARDZ and the EVAL-AD5676R2ARDZ both require the EVAL-SDP-CK1Z (SDP-K1) controller board, which are available for purchase from Analog Devices. For full details on the AD5675R and the AD5676R, see the AD5675R and AD5676R data sheets, which must be consulted in conjunction with this user guide when using the EVALAD5675RARDZ or the EVAL-AD5676R2ARDZ evaluation boards.

Features and Benefits

  • Full featured evaluation board for the AD5675/AD5675R
  • Various link options
  • PC control in conjunction with the Analog Devices, Inc., EVAL-SDP-CB1Z system demonstration platform (SDP)

Product Details

The EVAL-AD5675SDZ/EVAL-AD5675RSDZ evaluation boards help customers to quickly prototype new AD5675/AD5675R circuits and reduce design time. The AD5675/AD5675R operate from a single 2.7 V to 5.5 V supply. The AD5675R has an internal 2.5 V reference giving a maximum output voltage of 2.5 V or 5 V. The AD5675 does not have an internal reference; therefore, an ADR431 is provided on-board as a 2.5 V reference source. A different reference voltage can be applied via the EXT_REF SMB connector, if required.


Full data on the AD5675/AD5675R are available in the respective product data sheets, available from Analog Devices, which should be consulted in conjunction with UG-815 when using the evaluation boards.


The evaluation boards interface to the USB port of a PC via the SDP board. The Analysis Control Evaluation (ACE) software is available for use with the evaluation board to allow the user to program the AD5675/AD5675R.


The evaluation boards are compatible the EVAL-SDP-CB1Z Blackfin® SDP controller board (SDP-B), which is available for order on the Analog Devices website at www.analog.com.
