AD5663RBRMZ-5REEL7

Overview

The AD5663RBRMZ-5REEL7 is a dual 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 a temperature coefficient of 5 ppm/°C, providing a full-scale output of 5 V. The device guarantees monotonicity by design and includes a power-on reset circuit that ensures outputs power up to 0 V. It supports serial interfaces up to 50 MHz, including SPI, QSPI, Microwire, and DSP standards. Power consumption is typically 1.25 mW at 5 V, with per-channel power-down modes reducing current to 480 nA.

Feature Summary

• Dual 16-bit resolution with rail-to-rail buffered voltage outputs
• On-chip 2.5 V precision reference (5 ppm/°C) or external reference option
• Versatile 3-wire serial interface supporting clock rates up to 50 MHz
• Power-on reset to zero scale and software-selectable power-down modes

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 '-5' designation corresponds to the internal 2.5 V reference variant. Ensure compatibility with the required MSOP-10 package footprint and thermal management requirements for the operating temperature range of -40°C to +105°C.

Selection Notes

Select this component for applications requiring high resolution (16-bit) and low power consumption in a small form factor. The internal 2.5 V reference simplifies design by eliminating external reference components, suitable for systems needing a 0 V to 5 V output swing. Consider the AD5663R-3 variant if a lower 2.5 V full-scale output (from a 1.25 V internal reference) is preferred for lower voltage logic systems.

Part Context

This part belongs to the AD5623R/AD5643R/AD5663R nanoDAC family, which offers pin-compatible options for 12-bit, 14-bit, and 16-bit resolutions. The AD5663R represents the highest resolution tier in this series, sharing the same 10-lead MSOP and LFCSP packages and interface protocols as its lower-resolution counterparts.

Replacement Considerations

The AD5663RBRMZ-3 serves as a direct replacement if a 1.25 V internal reference (2.5 V full-scale output) is acceptable. Other family members like the AD5643R or AD5623R can replace this unit if lower resolution (14-bit or 12-bit) meets system accuracy requirements.
