The AD5696, a member of the nanoDAC+™ family, is a low power, quad, 16-bit buffered voltage output DAC. The device includes a gain select pin giving a full-scale output of 0V to VREF (gain = 1) or 0V to 2VREF (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 package and in a TSSOP package.
The AD5696 incorporates a power-on reset circuit and a RSTSEL pin; the RSTSEL pin ensures that the DAC outputs power up to zero scale or midscale and remain at that level until a valid write takes place. The part contains a per-channel power-down feature that reduces the current consumption of the device in power-down mode to 4 µA at 3 V.
The AD5696 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 Lifecycle Production
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
Evaluation Kits (1)
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.

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.
