AD5673RBCPZ-1-RL7

Overview

The AD5673RBCPZ-1-RL7 is a 16-channel, 12-bit nanoDAC+ with an integrated voltage reference. It features a 2 ppm/°C temperature coefficient for the internal 2.5V reference and supports I2C interface communication. The device operates on a single supply voltage ranging from 2.7V to 5.5V and includes a gain selection pin to achieve full-scale outputs of either 2.5V or 5.0V. Packaged in a 4mm x 4mm LFCSP-28, it incorporates an up-time reset circuit ensuring outputs start at zero or mid-scale upon power-up.

Feature Summary

• 16-channel, 12-bit resolution with buffered voltage output
• Integrated 2.5V reference with 2 ppm/°C temperature coefficient
• User-selectable gain (1x or 2x) for 2.5V or 5.0V full-scale output
• 400kHz I2C-compatible serial interface

Applications

• Optical transceivers
• Base station power amplifiers
• Process control PLC input/output cards
• Data acquisition systems

Procurement Notes

Verify the specific suffix -RL7 indicates reel packaging when sourcing. Confirm RoHS compliance status through official documentation as required by regional regulations. Ensure the ordering part number matches the exact channel count and package type specified in design requirements before procurement.

Selection Notes

Select this component for applications requiring multiple low-power DAC channels in a compact footprint. The 2 ppm/°C reference TC makes it suitable for precision instrumentation where drift must be minimized. Verify that the 400kHz I2C speed meets system bus timing constraints and that the 2.7V to 5.5V supply range aligns with available board power rails.

Part Context

This part belongs to the AD567xR family of nanoDACs from Analog Devices. The family shares common architectural features including low power consumption, monotonicity guarantees, and similar packaging options. The AD5673R specifically denotes the 16-channel variant within this series, distinguishing it from lower channel count models like the AD5671R.

Replacement Considerations

Check for direct cross-references within the AD567xR family if channel counts differ. Verify pin compatibility and software register maps when substituting with other 16-channel DACs from different manufacturers to ensure seamless integration without hardware redesign.
