The AD5693R / AD5692R / AD5691R / AD5693, members of the nanoDAC+® family, are low power, single-channel, 16-/14-/12-bit buffered voltage output DACs. The devices, except the AD5693, include an enabled by default internal 2.5 V reference, offering 2 ppm/°C drift. The output span can be programmed to be 0 V to VREF or 0 V to 2 × VREF. All devices operate from a single 2.7 V to 5.5 V supply and are guaranteed monotonic by design. The devices are available in a 2.00 mm × 2.00 mm, 8-lead LFCSP or a 10-lead MSOP.
The internal power-on reset circuit ensures that the DAC register is written to zero scale at power-up while the internal output buffer is configured in normal mode. The AD5693R / AD5692R / AD5691R / AD5693 contain a power-down mode that reduces the current consumption of the device to 2 μA (maximum) at 5 V and provides software selectable output loads.
The AD5693R / AD5692R / AD5691R / AD5693 use an I2C interface. Some device options also include an asynchronous RESET pin and a VLOGIC pin, allowing 1.8 V compatibility.

Product Lifecycle Recommended for New Designs
This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
Evaluation Kits (1)
The EVAL-AD5693RSDZ is designed to help customers quickly prototype AD5693R circuits and reduce design time. The AD5693R operates from a single 2.7 V to 5.5 V supply. The AD5693R incorporates an internal 2.5 V on-board reference to give an output voltage span of 2.5 V or 5 V.
The EVAL-AD5693RSDZ evaluation board interfaces to the USB port via the SDP board. The analysis control evaluation (ACE) software is available for download from the EVAL-AD5693RSDZ product page to use with the evaluation board to allow the user to program the AD5693R. The EVAL-AD5693RSDZ evaluation board requires the purchase of the EVAL-SDP-CB1Z (SDP-B) board or the EVAL-SDP-CS1Z (SDP-S) board.
For full details, consult the AD5693R data sheet, which must be used in conjunction with user guide (UG-675) when using the 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.
