Overview
The AD5692RACPZ-RL7 is a single-channel, 14-bit buffered voltage output digital-to-analog converter (DAC) from the nanoDAC+ family. It operates on a single 2.7 V to 5.5 V supply and features an internal 2.5 V reference with a typical drift of 2 ppm/°C. The device utilizes an I2C serial interface for data transfer. Key electrical specifications include a maximum integral nonlinearity (INL) of ±4 LSB and differential nonlinearity (DNL) of ±1 LSB. The output buffer provides high drive capability up to 20 mA and supports selectable spans of 0 V to VREF or 0 V to 2 × VREF. Power consumption in power-down mode is limited to 2 µA maximum.
Feature Summary
- 14-bit resolution with ±4 LSB INL and ±1 LSB DNL
- Internal 2.5 V reference with 2 ppm/°C typical temperature coefficient
- I2C serial interface with software-selectable gain (×1 or ×2)
- Ultrasmall 8-lead LFCSP package (2 mm × 2 mm)
Applications
- Process control systems
- Data acquisition systems
- Programmable voltage sources
- Digital gain and offset adjustment
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current documentation to confirm pinout options such as LDAC, RESET, or VLOGIC configurations. Ensure the selected variant matches the required hardware reset or logic voltage compatibility needs for the target design.
Selection Notes
Select this component when a single-channel DAC with 14-bit accuracy and low drift is required. The internal reference eliminates the need for external precision references. Verify that the system I2C bus speed does not exceed 400 kHz and that the load requirements stay within the 20 mA drive capability.
Part Context
This part belongs to the AD5693R/AD5692R/AD5691R family, which shares common architectural features including segmented string DAC architecture and I2C connectivity. The AD5692R specifically offers 14-bit resolution, positioned between the 12-bit AD5691R and the 16-bit AD5693R in terms of performance and code range.
Replacement Considerations
Direct functional substitutes within the same family include the AD5691R (12-bit) and AD5693R (16-bit), provided the resolution difference is acceptable. Other variants in the series may differ by package type or additional pins like RESET or VLOGIC.
