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.

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.
