AD5669RBCPZ-2-RL7

Overview

The AD5669RBCPZ-2-RL7 is an octal, 16-bit buffered voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an on-chip 2.5 V reference with a temperature coefficient of 5 ppm/°C, enabling a full-scale output range of 5 V. The device operates on a single supply voltage ranging from 4.5 V to 5.5 V when using the internal reference. It incorporates a power-on reset circuit that ensures outputs initialize to zero scale or midscale. The part supports I2C-compatible serial interfaces and includes three power-down modes, reducing current consumption to 400 nA at 5 V.

Feature Summary

• Octal architecture providing eight independent 16-bit DAC channels in a compact package.
• Integrated 2.5 V reference with low drift of 5 ppm/°C for stable output performance.
• Power-on reset functionality guarantees safe initialization to zero scale or midscale upon startup.
• Low power consumption with dedicated power-down modes achieving currents as low as 400 nA.

Applications

• Process control systems requiring multi-channel signal generation
• Data acquisition systems needing precise analog output scaling
• Portable battery-powered instruments utilizing low-power operation
• Programmable voltage and current sources for industrial automation

Procurement Notes

Verify the specific suffix -2-RL7 confirms the inclusion of the 2.5 V internal reference and reel packaging. Confirm the LFCSP-16 package variant matches the design requirements. Check for moisture sensitivity levels and reflow soldering profile compliance before integration into the manufacturing process.

Selection Notes

Select this component when eight synchronized 16-bit outputs are required within a small footprint. Ensure the system supply voltage falls within the 4.5 V to 5.5 V range mandated by the internal 2.5 V reference configuration. Consider the external reference option if wider supply voltage flexibility below 4.5 V is necessary.

Part Context

This part belongs to the denseDAC family, designed for high channel density in space-constrained applications. It shares functional similarities with the AD5629R but offers higher 16-bit resolution compared to the 12-bit alternative. The device integrates advanced features like hardware LDAC and CLR functions for robust system control.

Replacement Considerations

The AD5629R serves as a lower-resolution alternative within the same family. For pin-compatible replacements with different resolutions or interface options, consult the official Analog Devices cross-reference documentation to ensure electrical compatibility.
