Overview
The AD5667RBCPZ-R2 is a dual, 16-bit buffered voltage-output digital-to-analog converter (DAC) from the nanoDAC family. It features an on-chip 1.25 V reference with a 5 ppm/°C temperature coefficient, providing a full-scale output range of 2.5 V. Operating on a single 2.7 V to 5.5 V supply, it guarantees monotonicity by design and includes a power-on reset circuit that ensures outputs start at 0 V. The device utilizes a 2-wire I2C-compatible serial interface supporting standard, fast, and high-speed modes.
Feature Summary
- Dual-channel 16-bit resolution with rail-to-rail buffered voltage outputs
- Integrated 1.25 V precision reference with 5 ppm/°C temperature coefficient
- I2C-compatible serial interface supporting up to 3.4 MHz high-speed mode
- Power-on reset to zero scale and per-channel software-selectable power-down
Applications
- Process control systems
- Data acquisition systems
- Portable battery-powered instruments
- Digital gain and offset adjustment circuits
- Programmable voltage and current sources
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and internal reference configuration. Ensure compatibility with system voltage levels and I2C bus timing requirements before procurement.
Selection Notes
Select this component for applications requiring high accuracy and low power consumption in a compact form factor. The integrated reference simplifies design by eliminating external components, while the guaranteed monotonicity makes it suitable for closed-loop control systems.
Part Context
This part belongs to the AD56x7R series of nanoDACs, which are pin-compatible with other members like the AD5627R and AD5647R. These devices share similar functional blocks but differ in resolution and reference configurations, allowing for flexible design scaling within the same footprint.
Replacement Considerations
Direct replacements include other AD56x7R series parts such as AD5667RBRMZ-2 for different packaging or AD5667 without the R suffix if an external reference is acceptable. Verify pinout and electrical specifications match the original design requirements.
