AD5675RARUZ-REEL7

Overview

The AD5675RARUZ-REEL7 is an octal, 16-bit buffered voltage output digital-to-analog converter (DAC) from Analog Devices. It features a high-performance architecture with a maximum integral nonlinearity (INL) of ±3 LSB and a total unadjusted error (TUE) of ±0.14% FSR. The device includes a low-drift 2.5 V internal reference with a typical temperature coefficient of 2 ppm/°C. Operating on a single 2.7 V to 5.5 V supply, it supports a user-selectable gain of 1 or 2 via the GAIN pin or bit, enabling full-scale outputs of 2.5 V or 5 V. Communication is handled through a 400 kHz I²C-compatible serial interface.

Feature Summary

• Octal 16-bit resolution with ±3 LSB maximum INL and ±0.14% FSR TUE
• Integrated 2.5 V reference with 2 ppm/°C typical drift
• User-selectable gain (×1 or ×2) for 2.5 V or 5 V full-scale output
• 400 kHz I²C serial interface with 1.8 V logic compatibility

Applications

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

Procurement Notes

Verify that the REEL7 suffix indicates tape-and-reel packaging rather than tube packaging when sourcing this specific part number. Confirm the A-grade or B-grade performance specifications required for the application against the datasheet Table 3 limits. Ensure the ordering documentation matches the 20-lead TSSOP package type associated with the RARUZ designation.

Selection Notes

Select this component for applications requiring multiple synchronized analog outputs with high relative accuracy. The internal reference eliminates the need for external precision voltage sources, simplifying board layout. Consider the 2.7 V to 5.5 V supply range and 1.8 V logic compatibility for interfacing with various microcontrollers. Verify thermal dissipation requirements given the 98.65°C/W θJA in the TSSOP package.

Part Context

This device belongs to the nanoDAC+ family, which integrates precision references and buffered outputs into compact packages. The AD5675R variant specifically provides 16-bit resolution across eight channels, distinguishing it from the 12-bit AD5671R. The 'R' suffix denotes the inclusion of the internal 2.5 V reference, while 'U' specifies the TSSOP package form factor.

Replacement Considerations

The AD5675RBRUZ is a documented alternative offering the same electrical characteristics but packaged in LFCSP format instead of TSSOP. Designers must account for the different pinout and thermal pad requirements when substituting between these package types.
