AD5664RBRMZ-3REEL7

Overview

The AD5664RBRMZ-3REEL7 is a quad, 16-bit buffered voltage-output digital-to-analog converter (DAC) from Analog Devices. It operates on a single 2.7 V to 5.5 V supply and features an on-chip 1.25 V reference with 5 ppm/°C temperature coefficient, yielding a 2.5 V full-scale output range. The device supports serial interfaces up to 50 MHz, including SPI, QSPI, Microwire, and DSP standards. Key specifications include ±1 LSB differential nonlinearity, rail-to-rail output swing, and per-channel power-down modes reducing current consumption to 480 nA at 5 V.

Feature Summary

• Quad 16-bit resolution with guaranteed monotonicity by design
• On-chip 1.25 V precision reference (5 ppm/°C) for 2.5 V full-scale output
• Versatile 3-wire serial interface compatible with standard protocols up to 50 MHz
• Per-channel power-down functionality with software-selectable output loads

Applications

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

Procurement Notes

Verify the specific suffix REEL7 indicates tape-and-reel packaging when sourcing. Confirm the -3 suffix corresponds to the 1.25 V internal reference variant. Check for RoHS compliance status in the latest manufacturer documentation before finalizing procurement plans.

Selection Notes

Select this component for applications requiring four independent 16-bit channels in a compact footprint. Ensure the 2.5 V output range meets system requirements; use the -5 suffix variant if a 5 V range is needed. Verify that the 50 MHz serial clock speed aligns with the host microcontroller's capabilities.

Part Context

This part belongs to the nanoDAC® family, designed for low-power, space-constrained environments. It shares pin compatibility with other members of the series, such as the AD5624R and AD5644R, which offer 12-bit and 14-bit resolutions respectively, allowing for design flexibility across different accuracy requirements.

Replacement Considerations

Publicly confirmed substitutes are not identified in the provided source material. For equivalent functionality, consider other quad DACs from Analog Devices or verify pin-compatible alternatives through official distributor cross-reference tools.
