AD5672RBRUZ-REEL7

Overview

The AD5672RBRUZ-REEL7 is an octal, 12-bit buffered voltage output digital-to-analog converter (DAC) from Analog Devices. It features a high-performance architecture with a maximum relative accuracy (INL) of ±1 LSB and a total unadjusted error (TUE) of ±0.14% of full-scale range. The device integrates a low-drift 2.5 V reference with a typical temperature coefficient of 2 ppm/°C. Operating on a single supply between 2.7 V and 5.5 V, it supports a user-selectable gain of 1 or 2, enabling full-scale outputs of 2.5 V or 5 V respectively. The component utilizes a 50 MHz SPI interface with readback capabilities and operates within a temperature range of −40°C to +125°C.

Feature Summary

• Octal 12-bit resolution with ±1 LSB maximum INL and ±0.14% max TUE
• Integrated 2.5 V internal reference with 2 ppm/°C typical drift
• User-selectable gain (1x or 2x) for 2.5 V or 5 V full-scale output ranges
• 50 MHz SPI interface with daisy-chain and readback support

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and reel specifications. Confirm that the required logic voltage levels align with the 1.8 V compatibility feature. Ensure ESD precautions are observed during handling due to the sensitivity of the CMOS nanoDAC+ structure.

Selection Notes

Select this component when eight independent analog channels are required in a compact form factor. The integrated reference simplifies design by eliminating external precision components. Verify that the 50 MHz SPI speed meets the system timing requirements and that the 2.7 V to 5.5 V supply range matches the available power rails.

Part Context

This part belongs to the AD5672R/AD5676R nanoDAC+ family, which provides high channel density and precision in small packages. The AD5672R specifically offers 12-bit resolution, whereas the AD5676R variant provides 16-bit resolution. Both share similar interfaces and reference architectures but differ in linearity specifications and code ranges.
