AD5669RBCBZ-1-RL7

Overview

The AD5669RBCBZ-1-RL7 is an octal, 16-bit buffered voltage-output digital-to-analog converter (DAC) from Analog Devices. It features a 2.6 mm × 2.6 mm 16-ball WLCSP package and integrates a 1.25 V reference with 5 ppm/°C temperature coefficient, yielding a 2.5 V full-scale output range. The device operates on a single 2.7 V to 5.5 V supply, supports I2C interfaces at standard (100 kHz) and fast (400 kHz) modes, and includes power-on reset to zero scale. Power consumption drops to 400 nA at 5 V in power-down mode.

Feature Summary

• Octal architecture with 16-bit resolution and rail-to-rail buffered voltage outputs
• Integrated 1.25 V reference providing 5 ppm/°C stability for a 2.5 V full-scale range
• I2C-compatible serial interface supporting standard and fast modes
• Power-down capability reducing current to 400 nA at 5 V

Applications

• Process control systems
• Data acquisition systems
• Portable battery-powered instruments
• Programmable voltage and current sources

Procurement Notes

Verify the suffix -1-RL7 confirms the 1.25 V internal reference configuration and reel packaging. Ensure the WLCSP-16 footprint matches the PCB layout, as the exposed pad requires direct connection to ground for proper thermal and electrical performance.

Selection Notes

Select this component when eight independent 16-bit channels are required in a minimal footprint. The 1.25 V reference limits the maximum output swing to 2.5 V; use the -2 or -3 variants if a 5 V full-scale range is necessary. Verify that the system supply voltage remains within the 2.7 V to 5.5 V operational window.

Part Context

This part belongs to the denseDAC family, designed for high channel density in space-constrained applications. The BC prefix indicates the 16-ball WLCSP package variant, distinguishing it from LFCSP or TSSOP options. The -1 suffix specifically denotes the internal 1.25 V reference selection.

Replacement Considerations

Publicly confirmed substitutes include other AD5669R variants with different packages (LFCSP, TSSOP) or reference voltages (-2, -3). Cross-model replacements like the AD5629R offer lower 12-bit resolution but share similar pinouts and functionality.
