The AD5306 / AD5316 / AD5326 are quad 8-/10-/12-bit buffered voltage output DACs in 16-lead TSSOP packages that operate from a single 2.5 V to 5.5 V supply, consuming 500 μA at 3 V. Their on-chip output amplifiers allow rail-to-rail output swing with a slew rate of 0.7 V/μs. A 2-wire serial interface, which operates at clock rates up to 400 kHz, is used. This interface is SMBus-compatible at VDD < 3.6 V. Multiple devices can be placed on the same bus.
Each DAC has a separate reference input that can be configured as buffered or unbuffered. The outputs of all DACs can be updated simultaneously using the asynchronous LDAC input. The parts incorporate a power-on reset circuit that ensures the DAC outputs power up to 0 V and remain there until a valid write to the device takes place. The software clear function clears all DACs to 0 V. The parts contain a power-down feature that reduces the current consumption of the device to 300 nA @ 5 V (90 nA @ 3 V).
All three parts have the same pinout, which allows users to select the amount of resolution appropriate for their application without redesigning their circuit board.

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 AD5326 evaluation board is designed to help users quickly prototype new AD5326 circuits and reduce design time. The AD5326 operates from a single 2.5 V to 5.5 V supply.
Full data is available in the AD5326 data sheet, which must be consulted in conjunction with UG-977 when using the evaluation board.
The evaluation board interfaces to the USB port of a PC via the SDP-B controller board (EVAL-SDP-CB1Z). Software is supplied with the evaluation board to allow the user to program the AD5326.
This evaluation board requires the SDP-B controller board (EVAL-SDP-CB1Z).
Tools & Simulations
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.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
