AD5667BRMZ-REEL7

Overview

The AD5667BRMZ-REEL7 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 I2C-compatible serial interface supporting standard (100 kHz), fast (400 kHz), and high-speed (3.4 MHz) modes. The device includes hardware LDAC and CLR functions, per-channel power-down capability reducing current to 480 nA at 5 V, and a power-on reset circuit ensuring outputs start at 0 V. It is housed in a 10-lead MSOP package.

Feature Summary

• Dual 16-bit resolution with rail-to-rail output swing
• I2C-compatible serial interface with up to 3.4 MHz clock speed
• Per-channel power-down mode for low-power applications
• Hardware LDAC and CLR pins for synchronized updates and zero-scale clearing

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 that the specific part number corresponds to the external reference version of the AD5667 series. Confirm the package type is MSOP-10 and check for RoHS compliance status. Ensure the ordering suffix matches the required tape and reel quantity specifications provided by the manufacturer.

Selection Notes

Select this component when a dual-channel, 16-bit DAC with I2C connectivity is required. It is suitable for designs needing guaranteed monotonicity and low power consumption. Consider the AD5667R variant if an internal reference source is preferred over an external one.

Part Context

This component belongs to the nanoDAC family, which offers pin-compatible options across 12-, 14-, and 16-bit resolutions. The AD5667 series provides dual channels in compact packages, including LFCSP and MSOP, designed for space-constrained portable and industrial applications.

Replacement Considerations

The AD5663 is a compatible alternative offering similar performance with an SPI interface instead of I2C.
