AD5676RBCBZ-RL

Overview

The AD5676RBCBZ-RL is an octal, 16-bit buffered voltage output digital-to-analog converter (DAC) from Analog Devices. It features a 2.5 V internal reference with a typical temperature coefficient of 2 ppm/°C and supports user-selectable gain settings of 1 or 2 for full-scale outputs of 2.5 V or 5 V. The device operates on a single 2.7 V to 5.5 V supply and includes a power-on reset circuit ensuring outputs start at zero or midscale. It utilizes a 50 MHz SPI interface with readback capabilities and incorporates a power-down mode reducing current consumption to 1 µA typical.

Feature Summary

• Octal architecture providing eight independent 16-bit channels in a compact footprint.
• Integrated 2.5 V precision reference with low drift of 2 ppm/°C typical.
• High relative accuracy with Integral Nonlinearity (INL) specified at ±3 LSB maximum for B grade.
• Flexible serial interface supporting SPI up to 50 MHz with daisy-chain and readback functions.

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 official documentation to confirm package type and reel specifications. Ensure compatibility with system requirements regarding logic voltage levels and thermal management for the selected package variant.

Selection Notes

Select this component for applications requiring high channel density and precise multi-channel voltage generation. Consider the B grade specifications for INL and offset error limits when designing for tight tolerance requirements. Verify that the external load conditions remain within the capacitive and resistive stability limits defined in the datasheet.

Part Context

This part belongs to the nanoDAC+ family, designed for low-power, high-performance data conversion. The AD5676R variant specifically offers 16-bit resolution with an integrated reference, distinguishing it from external reference versions. It complements other devices like the AD5672R which provides 12-bit resolution.

Replacement Considerations

The AD5676ARUZ serves as a pin-compatible alternative within the same series. Verify electrical parameter alignment, particularly INL and offset error grades, before substitution.
