AD5663RBRMZ-3REEL7

Overview

The AD5663RBRMZ-3REEL7 is a dual-channel, 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 integrated 1.25 V reference with a 5 ppm/°C temperature coefficient, yielding a 2.5 V full-scale output range. The device guarantees monotonicity by design and includes a power-on reset circuit that forces outputs to zero scale upon initialization. It supports serial interfaces up to 50 MHz, including SPI, QSPI, Microwire, and DSP standards.

Feature Summary

• Dual 16-bit resolution with rail-to-rail buffered voltage outputs
• Integrated 1.25 V precision reference (5 ppm/°C)
• User-selectable external or internal reference input
• Per-channel software-selectable power-down modes

Applications

• Process control systems
• Portable battery-powered instruments
• Programmable voltage and current sources
• Digital gain and offset adjustment circuits

Procurement Notes

Verify the specific suffix 'REEL7' indicates tape-and-reel packaging when sourcing components. Confirm the '-3' designation corresponds to the 1.25 V internal reference variant. Ensure compatibility with the required operating voltage range of 2.7 V to 5.5 V for the target application environment.

Selection Notes

Select this component for applications requiring high-resolution dual-channel conversion with low power consumption. The integrated 1.25 V reference simplifies design by eliminating the need for external reference components while maintaining stability. Consider the MSOP-10 package dimensions for PCB layout constraints.

Part Context

This part belongs to the AD5623R/AD5643R/AD5663R nanoDAC family. The AD5663R specifically provides 16-bit resolution, distinguishing it from the 12-bit AD5623R and 14-bit AD5643R variants within the same pin-compatible series.

Replacement Considerations

The AD5663ARMZ serves as a pin-compatible alternative but utilizes an external reference configuration rather than an integrated one.
