AD5664RBRMZ-5REEL7

Overview

The AD5664RBRMZ-5REEL7 is a quad, 16-bit buffered voltage-output digital-to-analog converter (DAC) from the nanoDAC family. It operates on a single 2.7 V to 5.5 V supply and features an on-chip 2.5 V reference with 5 ppm/°C temperature coefficient. The device supports serial interfaces up to 50 MHz, including SPI, QSPI, Microwire, and DSP standards. Key specifications include a maximum settling time of 7 μs, guaranteed monotonicity by design, and power-on reset to zero scale. It is housed in a 10-lead MSOP package.

Feature Summary

• Quad 16-bit resolution with rail-to-rail output swing
• On-chip 2.5 V precision reference (5 ppm/°C)
• Versatile 3-wire serial interface supporting up to 50 MHz clock rates
• Per-channel power-down mode reducing current consumption to 480 nA at 5 V

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and reel specifications. Ensure compatibility with system voltage requirements and interface protocols before integration.

Selection Notes

Select this component for applications requiring high-resolution quad DAC outputs in a compact surface-mount package. Consider the internal 2.5 V reference capability if external reference components are to be minimized. Verify that the 50 MHz serial interface speed meets the system's timing constraints.

Part Context

This part belongs to the AD56x4R series of nanoDACs, which includes 12-bit (AD5624R), 14-bit (AD5644R), and 16-bit (AD5664R) variants. All members share pin-compatible packages and similar functional architectures, differing primarily in resolution and linearity specifications.

Replacement Considerations

Check for direct pin-compatible alternatives within the AD56x4R family or other quad DAC offerings from Analog Devices. Verify that any substitute matches the 16-bit resolution, serial interface compatibility, and operating voltage range.
