AD5675RBRUZ-REEL7

Overview

The AD5675RBRUZ-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% of full-scale range. 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 user-selectable gain settings of 1 or 2 via the GAIN pin or bit, allowing full-scale outputs of 2.5 V or 5 V respectively. The component utilizes a 400 kHz I²C-compatible serial interface and operates within a temperature range of −40°C to +125°C.

Feature Summary

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

Applications

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

Procurement Notes

Verify that the ordering suffix REEL7 corresponds to tape and reel packaging as specified in the manufacturer's documentation. Confirm the B grade designation indicates the specific accuracy tier required for the application. Ensure the 20-lead TSSOP package type matches the PCB footprint constraints. Cross-reference the datasheet revision C specifications against current procurement requirements.

Selection Notes

Select this component when eight independent 16-bit channels are required in a compact form factor. The integrated 2.5 V reference eliminates the need for external precision references, reducing board space. Verify that the 2.7 V to 5.5 V supply range aligns with the system power architecture. Consider the 1 μA power-down mode for applications requiring low standby current consumption.

Part Context

The AD5675RBRUZ-REEL7 belongs to the nanoDAC+ family, which integrates high-precision DACs with low-drift references. This specific part is the I²C-enabled, 16-bit variant of the AD5675R series. It shares architectural similarities with the SPI-based AD5676R but offers simplified interfacing through the two-wire serial protocol. The B grade denotes tighter performance specifications compared to the A grade.

Replacement Considerations

The AD5675ARUZ serves as a parameter-equivalent alternative with slightly different linearity specifications. For SPI interface requirements, the AD5676R provides comparable functionality with a different communication protocol. Verify pinout compatibility and register mapping before substituting these components.
