Overview
The AD5669RACPZ-2-RL7 is an octal, 16-bit buffered voltage-output digital-to-analog converter (DAC) from the denseDAC family. It features a 2.7 V to 5.5 V supply range and integrates a 2.5 V on-chip reference with a temperature coefficient of 5 ppm/°C, enabling a 0 V to 5 V output swing. The device supports I2C-compatible serial interfaces at standard (100 kHz) and fast (400 kHz) modes. Key specifications include a settling time of 7 µs, guaranteed monotonicity by design, and power-down currents as low as 400 nA at 5 V. It is housed in a 16-lead LFCSP package.
Feature Summary
- Octal architecture providing eight independent 16-bit DAC channels.
- Integrated 2.5 V reference with 5 ppm/°C temperature stability.
- I2C-compatible interface supporting standard and fast mode operations.
- Power-on reset circuitry ensuring outputs initialize to zero scale.
Applications
- Process control systems
- Data acquisition systems
- Portable battery-powered instruments
- Programmable voltage and current sources
Procurement Notes
Verify the suffix -2 confirms the internal 2.5 V reference selection for 5 V full-scale operation. Confirm the ACPZ package designation corresponds to the 16-lead LFCSP form factor. Ensure the RL7 suffix matches the required reel packaging quantity for production integration.
Selection Notes
Select this component when eight isolated 16-bit outputs are required within a compact footprint. The integrated 2.5 V reference simplifies board layout compared to external reference solutions. Verify that the 2.7 V to 5.5 V supply range aligns with the system's available power rails and that I2C bus speeds meet communication requirements.
Part Context
This part belongs to the AD5629R/AD5669R denseDAC series, which offers high channel density in small packages. The AD5669R variant specifically provides 16-bit resolution, distinguishing it from the 12-bit AD5629R. The -2 suffix indicates the specific internal reference voltage configuration.
Replacement Considerations
The AD5669RBCPZ-2500R7 serves as a functional replacement, offering identical electrical characteristics but utilizing a 16-LFCSP-WQ (4x4 mm) package instead of the standard LFCSP.
