AD5676RBCPZ-RL

Overview

The AD5676RBCPZ-RL is an octal, 16-bit buffered voltage output digital-to-analog converter (DAC) from Analog Devices. It features a low-drift 2.5 V internal reference with a typical temperature coefficient of 2 ppm/°C and a user-selectable gain of 1 or 2, providing full-scale outputs of 2.5 V or 5 V respectively. The device operates on a single 2.7 V to 5.5 V supply and supports SPI interfaces up to 50 MHz. Packaged in a 20-lead LFCSP, it includes power-on reset circuits and individual channel power-down modes that reduce current consumption to 1 µA typical.

Feature Summary

• Octal architecture with 16-bit resolution and ±3 LSB maximum INL
• Integrated 2.5 V reference with 2 ppm/°C drift
• SPI interface supporting 50 MHz clock rates
• Power-down mode reduces consumption to 1 µA typical

Applications

• Optical transceivers
• Base station power amplifiers
• Process control 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 the package type matches the design footprint, as this part number indicates the LFCSP variant. Ensure the ordering suffix corresponds to the desired reel quantity and packaging format.

Selection Notes

Select the AD5676RBCPZ-RL when high channel density and precision are required in a compact form factor. The LFCSP package offers a small footprint suitable for space-constrained designs. Consider the A grade for tighter linearity specifications or the B grade if cost optimization is prioritized while maintaining functional accuracy.

Part Context

This component belongs to the nanoDAC+ family, which integrates precision DACs with on-chip references. The 'BCPZ' suffix denotes the 20-lead LFCSP package with RoHS compliance. The 'REEL7' suffix specifies the tape and reel packaging configuration used for automated surface-mount assembly processes.

Replacement Considerations

Direct pin-to-pin replacements within the same family include other AD5676R variants with different packages or grades. For external reference applications, the AD5676 series without the 'R' suffix is available but requires an external reference source.
