The AD5316R, a member of the nanoDAC® family, is a low power, quad, 10-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 lead lead frame chip scale package (LFCSP) and in a thin shrink small outline package (TSSOP).
The AD5316R also 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 device 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 AD5316R 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 Highlights

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 AD5316RDBZ evaluation board is designed to help users quickly prototype new AD5316R circuits and reduce design time. The AD5316R operates from a single 2.7 V to 5.5 V supply.
For full details, see the AD5316R data sheet, which must be consulted in conjunction with UG-969 when using the evaluation board.
The evaluation board interfaces to the USB port of a PC via the SDP-B board. Software is available to allow the user to program the AD5316R.

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.
