Overview
The AD5693RACPZ-1RL7 is a single-channel, 16-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 I2C serial interface with 1.8 V logic compatibility via the VLOGIC pin. The device includes an internal 2.5 V reference with a typical drift of 2 ppm/°C. Key electrical specifications include a maximum integral nonlinearity (INL) of ±2 LSB for Grade B, a settling time of 5 µs, and a low power consumption of 1.2 mW at 3.3 V. It is housed in an ultrasmall 2 mm × 2 mm, 8-lead LFCSP package.
Feature Summary
- 16-bit resolution with ±2 LSB maximum INL (Grade B)
- Internal 2.5 V reference with 2 ppm/°C typical drift
- I2C interface with 1.8 V VLOGIC compatibility
- Ultrasmall 8-lead LFCSP (2 mm × 2 mm) package
Applications
- Process controls
- Data acquisition systems
- Digital gain and offset adjustment
- Programmable voltage sources
- Optical modules
Procurement Notes
Verify the specific suffix '-1' against the manufacturer's ordering guide to confirm the presence of the VLOGIC pin and absence of the RESET pin, as these hardware options vary within the AD5693R family. Ensure the component grade (A or B) matches the required linearity specifications for the application.
Selection Notes
Select this component when high relative accuracy (±2 LSB INL) and low power consumption are required in a minimal footprint. The internal reference simplifies design by eliminating external components, while the 1.8 V logic compatibility facilitates integration with low-voltage microcontrollers.
Part Context
This part belongs to the AD5693R/AD5692R/AD5691R series, which offers 16-, 14-, and 12-bit resolutions respectively. The AD5693R variant provides the highest resolution within this specific nanoDAC+ lineup, sharing the same physical package and interface characteristics as its lower-resolution counterparts.
Replacement Considerations
Direct replacements within the same family include AD5693RACPZ-RL7 (standard I2C/LDAC) and AD5693RACPZ-2RL7 (RESET option). For SPI interfaces, consider the AD5683R series. Verify pinout compatibility regarding the VLOGIC versus RESET pin configuration before substitution.
