Overview
The AD5669RBRUZ-2 is an octal, 16-bit buffered voltage-output digital-to-analog converter (DAC) from Analog Devices. It features a 5 ppm/°C on-chip reference with an internal gain of 2, providing a full-scale output range of 5 V. The device operates on a single 4.5 V to 5.5 V supply and supports standard (100 kHz) and fast (400 kHz) I2C-compatible serial interfaces. Key specifications include a settling time of 7 µs, guaranteed monotonicity by design, and power-down modes reducing current consumption to 400 nA at 5 V.
Feature Summary
- Octal architecture with 16-bit resolution and rail-to-rail buffered voltage outputs.
- Integrated 2.5 V reference with 5 ppm/°C temperature coefficient.
- I2C interface supporting standard and fast modes with hardware LDAC and CLR functions.
- Power-on reset ensures outputs initialize to zero scale or midscale.
Applications
- Process control systems
- Data acquisition systems
- Portable battery-powered instruments
- Programmable voltage and current sources
Procurement Notes
Verify the specific suffix '-2' confirms the 2.5 V internal reference selection, as this dictates the required supply voltage range of 4.5 V to 5.5 V. Confirm package availability in TSSOP-16 format matches the design requirements. Cross-reference the manufacturer's ordering guide for current production status and lead times.
Selection Notes
Select the AD5669RBRUZ-2 when eight independent 16-bit channels are required with high precision. Ensure the system supply voltage meets the minimum 4.5 V threshold for the internal 2.5 V reference operation. Consider the 7 µs settling time and 320 kHz multiplying bandwidth for dynamic signal applications.
Part Context
This component belongs to the denseDAC family, designed for low-power, multi-channel data conversion. It shares the same pinout and interface logic with the 12-bit AD5629R variant, allowing for potential architectural flexibility within the same product line while offering higher resolution.
Replacement Considerations
Public confirmed substitute part numbers: AD5669RBRUZ-1 (1.25 V reference), AD5669RBRUZ-3 (midscale power-up).
FAQ
What is the full-scale output voltage range?
With the internal 2.5 V reference enabled, the full-scale output range is 0 V to 5 V.
How does the power-on reset function operate?
The device powers up with DAC outputs at 0 V due to the default clear code setting, remaining at this level until a valid write occurs.
What is the maximum capacitive load stability?
The output amplifiers are stable with capacitive loads up to 2 nF when unloaded, or up to 10 nF with a 2 kΩ resistive load.
