The AD5673R/AD5677R are low power, 16-channel, 12-/16-bit, buffered voltage output, digital-to-analog converters (DACs) that include a 2.5 V, 2 ppm/°C internal reference (enabled by default), and a gain select pin, resulting in 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 range and are guaranteed monotonic by design. The AD5673R/AD5677R are available in a 28-lead lead frame chip scale package (LFCSP) and incorporate a power-on reset (POR) circuit that ensures that the DAC outputs power up to and remain at zero scale or midscale until a valid write. The AD5673R/AD5677R contain a power-down mode that reduces the current consumption to 2 µA typical.

Evaluation Kits (1)
This user guide describes the operation of the EVALAD5677RSDZ for the AD5677R 16-bit, 16-channel, voltage output, digital-to-analog converter (DAC). The EVALAD5677RSDZ is also compatible with the AD5673R.
The EVAL-AD5677RSDZ allows users to quickly prototype AD5673R/AD5677R circuits and reduce design time. The AD5673R/AD5677R operates from a single 2.7 V to 5.5 V supply range. The AD5673R/AD5677R incorporates an internal 2.5 V reference to provide an output voltage of 2.5 V or 5 V. The EVAL-AD5677RSDZ also incorporates an additional on-board voltage reference.
The EVAL-AD5677RSDZ interfaces to the USB port of a PC via a system demonstration platform (SDP-B) board. The Analysis | Control | Evaluation (ACE) software is available for download from the EVAL-AD5677RSDZ product page. Use this software with the evaluation board to program the AD5673R/AD5677R. A peripheral module interface (PMOD) connection is also available to allow the connection of microcontrollers to the evaluation board without the SDP-B board. When a microcontroller is used through the PMOD connection, the SDP-B board must be disconnected, and the user is unable to operate the ACE software.
The EVAL-AD5677RSDZ is compatible with any Analog Devices SDP-B board, which can be purchased separately. A typical connection between the EVAL-AD5677RSDZ and the SDP-B controller board is shown in Figure 1.
For full details, see the AD5673R/AD5677R data sheet, which must be used in conjunction with this user guide when using the EVAL-AD5677RSDZ.
