Overview
The AD5696ARUZ, produced by Analog Devices Inc., is a member of the nanoDAC+ family. It is a low power, quad, 16-bit buffered voltage output Digital-to-Analog Converter (DAC). This device is designed to operate from a single 2.7 V to 5.5 V supply and is guaranteed monotonic by design. The AD5696ARUZ features high relative accuracy, low power consumption, and a versatile 2-wire serial I2C interface that operates at clock rates up to 400 kHz. It is available in a 3 mm × 3 mm LFCSP package and a 16-lead TSSOP package, making it suitable for a variety of applications requiring precise digital-to-analog conversion.

Key Features
- User-Selectable Gain: The AD5696ARUZ includes a gain select pin allowing for a full-scale output of 0V to VREF (gain = 1) or 0V to 2VREF (gain = 2).
- High Drive Capability: The device can drive up to 20 mA with 0.5 V from the supply rails.
- Power-On Reset and 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.
- Low Power Consumption: Operates at 1.8 mW at 3 V and reduces to 4 µA in power-down mode at 3 V.
- I2C-Compatible Serial Interface: Supports clock rates up to 400 kHz and includes 1.8 V, 3 V, and 5 V logic compatibility.
- Low Glitch and High ESD Rating: Features low glitch of 0.5 nV-sec and robust 3.5 kV HBM and 1.5 kV FICDM ESD rating.
Applications
- Digital Gain and Offset Adjustment: Ideal for applications requiring precise digital gain and offset adjustments.
- Programmable Attenuators: Suitable for use in programmable attenuators due to its high accuracy and low power consumption.
- Process Control (PLC I/O Cards): Used in process control systems, particularly in PLC I/O cards.
- Industrial Automation: Applicable in industrial automation systems where precise analog output is required.
- Data Acquisition Systems: Ideal for data acquisition systems due to its high accuracy and low power consumption).
