AD5667RBRMZ-1REEL7

Overview

The AD5667RBRMZ-1REEL7 is a dual-channel, 16-bit buffered voltage-output digital-to-analog converter (DAC) from the nanoDAC family. It integrates an on-chip 2.5 V reference with a temperature coefficient of 5 ppm/°C, enabling a full-scale output range of 5 V. The device operates on a single 2.7 V to 5.5 V supply and features an I²C-compatible serial interface supporting standard (100 kHz), fast (400 kHz), and high-speed (3.4 MHz) modes. Key specifications include ±1 LSB differential nonlinearity, ±12 LSB integral nonlinearity, and a typical settling time of 4 µs. It incorporates power-on reset to zero scale, per-channel power-down, and hardware LDAC/CLR functions.

Feature Summary

• Dual 16-bit resolution with integrated 2.5 V, 5 ppm/°C on-chip reference
• I²C-compatible serial interface with high-speed mode up to 3.4 MHz
• Guaranteed monotonic by design with rail-to-rail output swing
• Per-channel power-down reducing current consumption to 480 nA at 5 V

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and internal reference configuration. The 'BRMZ' designation indicates the MSOP-10 package with the 2.5 V internal reference. Confirm that the '1REEL7' suffix aligns with the required tape and reel quantity for manufacturing integration. Cross-reference the datasheet revision to ensure all electrical parameters match the design requirements.

Selection Notes

Select this component when a dual-channel, 16-bit DAC with an integrated precision reference is required in a compact surface-mount package. The AD5667RBRMZ variant provides a 2.5 V reference, suitable for applications needing a 0 V to 5 V output range. Ensure the system supports the I²C protocol at the desired clock speed. For designs requiring an external reference or different pinout compatibility, consider the AD5667 or other members of the nanoDAC family.

Part Context

This part belongs to the AD5627R/AD5647R/AD5667R series of low-power, dual nanoDACs. It shares functional similarities with the AD5667 but includes an on-chip reference, distinguishing it from the external-reference-only AD5667. The BRMZ suffix specifically denotes the 10-lead MSOP package with the 2.5 V reference option, offering a smaller footprint compared to LFCSP variants while maintaining pin compatibility within the series.

Replacement Considerations

The AD5667RBRMZ-2 is a compatible alternative within the same series, also featuring the 2.5 V internal reference and MSOP-10 package. Verify that any substitute maintains the same I²C addressability and timing characteristics. Other members of the nanoDAC family may offer different resolutions or reference options but require verification of pinout and electrical parameter compatibility.
