Overview
The AD5663RBRMZ-3 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, housed in a compact 10-lead MSOP package.
Feature Summary
- Dual 16-bit resolution with rail-to-rail buffered voltage outputs
- Integrated 1.25 V precision reference (5 ppm/°C) for 2.5 V full-scale output
- Guaranteed monotonic operation without missing codes
- Power-on reset ensures DAC outputs initialize to 0 V
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 '-3' confirms the internal 1.25 V reference configuration during procurement. Confirm the 'B' grade designation matches required accuracy specifications relative to the 'A' grade. Ensure the MSOP-10 package variant aligns with PCB footprint requirements. Cross-reference the datasheet revision to confirm pinout consistency.
Selection Notes
Select this component when a dual-channel 16-bit DAC with an integrated low-drift reference is required. The -3 suffix indicates a fixed 1.25 V internal reference; use the -5 suffix if a 2.5 V reference is needed. Consider the B grade accuracy limits for static performance. Verify interface compatibility with the host microcontroller's SPI or DSP mode.
Part Context
This part belongs to the AD5623R/AD5643R/AD5663R nanoDAC family, sharing pinouts and functionality across 12-, 14-, and 16-bit resolutions. The AD5663R represents the highest resolution tier within this series. The BRMZ suffix denotes the B grade accuracy level and the 10-lead MSOP surface-mount package type.
Replacement Considerations
The AD5663RBRMZ-5 serves as a direct replacement if a 2.5 V full-scale output range is acceptable instead of 2.5 V. For external reference applications, the AD5663ARMZ provides equivalent performance without an internal reference.
