The AD5693R/AD5692R/AD5691R, members of the nanoDAC+® family, are low power, single-channel, 16-/14-/12-bit buffered voltage output DACs. The devices 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 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 use an I2C interface. Some device options also include an asynchronous RESET pin and a VLOGIC pin, allowing 1.8 V compatibility.

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.
The evaluation board interfaces to the USB port via the SDP
board. Software is available with the evaluation board, which allows the user to easily program the AD5693R. This evaluation board requires the EVAL-SDP-CB1Z or EVAL-SDP-CS1Z board.
Full details on the device may be found in the AD5693R data sheet available from Analog Devices and should be consulted in conjunction with this user guide when using the evaluation board.
Chemical Analysis Precision Measurement and Control Innovation for ADI
ADI is committed to helping you design and build the very best measurement systems. Chemical analysis has many forms and
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.
