The AD5672R/AD5676R are low power, octal, 12-/16-bit buffered voltage output digital-to-analog converters (DACs). They include a 2.5 V, 2 ppm/°C internal reference (enabled by default) and a gain select pin giving a full-scale output of 2.5 V (gain = 1) or 5 V (gain = 2). The devices operate from a single 2.7 V to 5.5 V supply and are guaranteed monotonic by design. The AD5672R/AD5676R are available in a 20-lead TSSOP and in a 20-lead LFCSP and incorporate a power-on reset circuit and a RSTSEL pin that ensures that the DAC outputs power up to zero scale or midscale and remains there until a valid write. The AD5672R/AD5676R contain a power-down mode, reducing the current consumption to 1 µA typical while in power-down mode. The AD5676R is also available in a 16-ball WLCSP.

EVAL-AD5676R2ARDZ
Evaluating the AD5676R (SPI, TSSOP)
Product Detail
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.

EVAL-AD5676RARDZ
Evaluation Board for the AD5676R WLCSP
Product Detail
The EVAL-AD5676RARDZ allows users to quickly prototype AD5676R circuits and reduce design time. The AD5676R operates from a single 2.7 V to 5.5 V supply. The AD5676R incorporates an internal 2.5 V reference to give a full-scale output voltage of 2.5 V or 5 V. An ADR4525 is also provided on-board as a 2.5V reference source. A different external reference voltage can be applied via the EXT_REF SMB connector or test pin if needed.
The EVAL-AD5676RARDZ interfaces to the USB port of a PC via a system demonstration platform board (SDP-K1 ). The Analysis | Control | Evaluation (ACE) software is available for download from the EVAL-AD5676RARDZ product page to use with the evaluation board to allow the user to program the AD5676R. A peripheral module interface (PMOD) connection is also available to allow the connection of microcontrollers to the evaluation board without the SDP-K1 board. When a microcontroller is used through the PMOD connection, the SDP-K1 board must be disconnected, and the user is unable to operate the ACE software.
The EVAL-AD5676RARDZ is compatible with the EVAL-SDP-CK1Z (SDP-K1), which should be purchased separately. A typical connection between the EVAL-AD5676RARDZ and the SDP-B controller board is shown in the user guide. For full details, see the AD5676R data sheet, which must be used in conjunction with the user guide when using the EVAL-AD5676RARDZ.

EVAL-AD5676
AD5676 and AD5676R Evaluation Board
Product Detail
The EVAL-AD5676SDZ/EVAL-AD5676RSDZ evaluation boards help users to quickly prototype new AD5676/AD5676R circuits and reduce design time. The AD5676/AD5676R operate from a single 2.7 V to 5.5 V supply. The AD5676R has an internal 2.5 V reference giving a maximum output voltage of 2.5 V or 5 V. The AD5676 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 AD5676/AD5676R are available in the respective product data sheets, available from Analog Devices, which should be consulted in conjunction with user guide (UG-814) 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 AD5676/AD5676R.
The evaluation boards are compatible with the EVAL-SDP-CB1Z Blackfin® SDP controller board (SDP-B), which is available for order on the Analog Devices website at www.analog.com.
