AD5669RBCPZ-2500R7

Overview

The AD5669RBCPZ-2500R7 is an octal, 16-bit buffered voltage-output digital-to-analog converter (DAC) from Analog Devices. It features a 4 mm × 4 mm 16-lead LFCSP package and operates on a single 2.7 V to 5.5 V supply. The device incorporates an on-chip 2.5 V reference with a temperature coefficient of 5 ppm/°C, enabling a full-scale output range of 5 V. It supports I²C 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.

Feature Summary

• Octal architecture with eight independent 16-bit DAC channels in a compact 16-lead LFCSP package.
• Integrated 2.5 V internal reference with 5 ppm/°C stability for high precision applications.
• I²C-compatible serial interface supporting standard and fast mode operations.
• Power-on reset circuitry ensuring outputs initialize to zero scale or midscale.

Applications

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

Procurement Notes

Verify the specific suffix '2500R7' against official documentation to confirm packaging quantity and reel specifications. Ensure compatibility with the required operating voltage range of 2.7 V to 5.5 V. Confirm that the 16-lead LFCSP footprint matches the target PCB layout constraints. Check for moisture sensitivity levels if reflow soldering is planned.

Selection Notes

Select this component when eight simultaneous 16-bit outputs are required within space-constrained designs. The integrated 2.5 V reference eliminates the need for external precision references, reducing BOM cost. Consider the 7 µs settling time for bandwidth requirements. Verify that the I²C address configuration via the A0 pin fits the system bus topology.

Part Context

This part belongs to the AD5669R denseDAC family, which offers low-power solutions for multi-channel applications. It shares functional similarities with the AD5629R but provides higher 16-bit resolution. The device is designed for industrial environments with an operating temperature range of -40°C to +105°C.

Replacement Considerations

Direct substitutes include other variants within the AD5669R series such as AD5669RBCPZ-1-RL7 or AD5669RBRUZ-2-RL7, depending on the required reference voltage and package type (LFCSP vs. TSSOP). Ensure pinout compatibility and software register alignment when migrating between package styles.
