Overview
The AD5686RARUZ-RL7 is a quad, 16-bit buffered voltage output digital-to-analog converter (DAC) from the nanoDAC+ family. It features an internal 2.5 V reference with a typical temperature coefficient of 2 ppm/°C and supports SPI interfaces up to 50 MHz. The device operates on a single 2.7 V to 5.5 V supply, drawing 1.1 mA with the reference enabled. Key electrical parameters include ±2 LSB maximum INL, 5 µs settling time, and 90 dB SNR. It is housed in a 16-lead TSSOP package.
Feature Summary
- Quad 16-bit resolution with ±2 LSB maximum integral nonlinearity (INL)
- Integrated 2.5 V reference with 2 ppm/°C typical drift
- 50 MHz SPI interface with readback capability
- Rail-to-rail buffered outputs with 20 mA drive capability
Applications
- Process control I/O cards
- Base-station power amplifiers
- Optical transceivers
- Industrial automation systems
Procurement Notes
Verify the suffix -RL7 indicates reel packaging containing 1000 units. Confirm the R variant corresponds to the TSSOP-16 package rather than the LFCSP option. Ensure the specific grade (A or B) matches application requirements for accuracy specifications.
Selection Notes
Select this component when four independent 16-bit channels are required in a compact footprint. The internal reference simplifies design but requires checking if external precision references are needed for stricter drift applications. Verify logic voltage compatibility via the VLOGIC pin for 1.8 V, 3 V, or 5 V microcontrollers.
Part Context
This part belongs to the AD5686R series, which also includes variants with external references (AD5686) and different packages like LFCSP. The AD5686R specifically integrates the reference and uses SPI. Other members of the family include the 14-bit AD5685R and 12-bit AD5684R.
Replacement Considerations
Direct functional substitutes within the same package and specification include the AD5686ARUZ and AD5686BRUZ. For reel-packaged equivalents, consider AD5686ARUZ-RL7 or AD5686BRUZ-RL7. Cross-package replacements require mechanical re-design.
