AD5694R

Quad, 12-Bit nanoDAC+ with 2 ppm/°C Reference, I2C Interface

Manufactured by:

Product Details

The AD5694R is a low power, quad, 16-bit buffered voltage output DAC. The device includes 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 device operates 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 device is available in a 3 mm × 3 mm LFCSP and a TSSOP package.

The AD5694R also incorporates a power-on reset circuit and a RSTSEL pin that ensures 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 AD5694R uses a versatile 2-wire serial interface that operates at clock rates up to 400 kHz, and includes a VLOGIC pin intended for 1.8 V/3 V/5 V logic.

Product Details

This Evaluation Board is no longer available for ordering. Please see the AD5696R Evaluation Board.


The Evaluation board for the AD5694R contains a SDP connection and software allowing the AD5694R to be controlled from a SDP 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.

EVAL-AD5696R

EVAL-AD5696R Circuit Diagram

Product Details

The EVAL-AD5696RSDZ evaluation board is designed to help users quickly prototype AD5696R circuits and reduce design time. The AD5696R operates from a single 2.7 V to 5.5 V supply. The AD5696R incorporates an internal 2.5 V reference to give an output voltage of 2.5 V or 5 V. The EVAL-AD5696RSDZ evaluation board also incorporates additional voltage references.


The EVAL-AD5696RSDZ 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-AD5696RSDZ product page to use with the evaluation board to allow the user to program the AD5696R. 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-AD5696RSDZ evaluation board is compatible with any Analog Devices SDP board, which can be purchased separately.


For full details, see the AD5696R data sheet, which must be used in conjunction with UG-726 when using the EVAL-AD5696RSDZ evaluation board.
