AD5676RBRUZ

Overview

The AD5676RBRUZ 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 (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, providing 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 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
• 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 grade (A or B) required for your application, as performance specifications such as INL and offset error vary between grades. Confirm that the 20-lead TSSOP package aligns with your PCB footprint requirements. Ensure the design accounts for the exposed pad connection to ground for proper thermal management and electrical grounding.

Selection Notes

Select this component when eight independent 16-bit channels are needed in a compact form factor. Choose the A grade for tighter linearity specifications (±1.8 LSB max INL) or the B grade if standard precision is sufficient. Consider the internal reference's 2 ppm/°C drift against external reference options if higher stability is required over extreme temperature ranges.

Part Context

This part belongs to the nanoDAC+ family, which emphasizes high channel density and low power consumption. The AD5676R variant specifically offers 16-bit resolution compared to the 12-bit AD5672R. Both share similar pinouts and interfaces, allowing for potential design flexibility within the same product series while meeting different resolution requirements.
