AD5675RACPZ-REEL7

Overview

The AD5675RACPZ-REEL7 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. The device operates on a single 2.7 V to 5.5 V supply and includes a gain select pin for full-scale outputs of 2.5 V or 5 V. It utilizes a 400 kHz I²C-compatible serial interface with 1.8 V logic compatibility. Key performance metrics include a maximum INL of ±3 LSB, a settling time of 5 µs, and power consumption of 1.8 mA in normal mode.

Feature Summary

• Octal architecture with eight independent 16-bit DAC channels
• Integrated 2.5 V reference with 2 ppm/°C drift specification
• User-selectable gain of 1 or 2 via GAIN pin or bit control
• Power-down mode reduces current 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 INL and offset specifications vary between grades. Confirm that the LFCSP package matches your PCB footprint requirements. Ensure the I²C address configuration via A0 and A1 pins aligns with your system's bus topology to prevent addressing conflicts.

Selection Notes

Select this component when high channel count and precision are required in a compact form factor. The internal reference eliminates the need for external components, simplifying design. Consider the gain setting based on your desired output voltage range; Gain = 1 provides 0–2.5 V, while Gain = 2 provides 0–5 V. Verify thermal management needs given the operating temperature range of -40°C to +125°C.

Part Context

This part belongs to the nanoDAC+ family, designed for applications requiring multiple synchronized analog outputs. The 'R' suffix indicates the inclusion of the internal low-drift reference. The 'ACPZ' designation specifies the 20-lead LFCSP package type. This series complements SPI-based variants like the AD5676R, offering I²C connectivity for space-constrained designs.

Replacement Considerations

The AD5675BRUZ is a compatible alternative in the TSSOP-20 package. For non-reference versions, consider the AD5675. For SPI interface requirements, the AD5676R offers similar functionality with a different communication protocol.
