AD5671RBRUZ-REEL7

Overview

The AD5671RBRUZ-REEL7 is an octal, 12-bit buffered voltage output digital-to-analog converter (DAC) from Analog Devices. It features a 2.5 V internal reference with a typical drift of 2 ppm/°C and operates on a single 2.7 V to 5.5 V supply. The device uses a 400 kHz I²C-compatible serial interface and supports 1.8 V logic compatibility. Key electrical parameters include a maximum INL of ±1 LSB, a settling time of 8 µs, and an output current drive of 15 mA. It is housed in a 20-lead TSSOP package and includes power-on reset and power-down modes.

Feature Summary

• Octal architecture with eight independent 12-bit DAC channels
• Integrated 2.5 V reference with 2 ppm/°C temperature coefficient
• User-selectable gain of 1 or 2 for full-scale output ranges of 2.5 V or 5 V
• I²C serial interface with 400 kHz clock speed and 1.8 V logic compatibility

Applications

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

Procurement Notes

Verify the specific suffix REEL7 corresponds to reel packaging when sourcing. Confirm that the component matches the AD5671R variant rather than the AD5675R, as they share the same pinout but differ in resolution and accuracy specifications. Ensure the ordering documentation explicitly states the 12-bit specification.

Selection Notes

Select this component when multiple low-channel-count DACs are required in a compact form factor. The integrated reference eliminates external components, reducing board space. Verify that the 12-bit resolution and ±1 LSB INL meet system accuracy requirements. Check that the 15 mA output drive capability is sufficient for the intended load impedance.

Part Context

This part belongs to the nanoDAC+ family, which integrates precision references and amplifiers into small packages. The AD5671R is the 12-bit counterpart to the 16-bit AD5675R within the same series. Both variants utilize identical interfaces and pinouts, allowing for potential design flexibility between resolution grades.

Replacement Considerations

The AD5675R is a functional pin-compatible alternative offering 16-bit resolution. Other octal DACs may require level shifting or different interface configurations. Verify that any substitute maintains the 2.7 V minimum supply voltage and I²C protocol compatibility.
