AD5677RBCPZ-2-RL7

Overview

The AD5677RBCPZ-2-RL7 is a quad-channel, 16-bit buffered voltage output Digital-to-Analog Converter (DAC) from Analog Devices. It integrates a high-precision internal reference with a temperature coefficient of 2 ppm/°C and supports an I²C serial interface. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V and features a user-selectable gain configuration for full-scale outputs of either 2.5 V or 5.0 V. Packaged in a compact 28-lead LFCSP, it includes power-on reset circuitry to ensure safe initial states.

Feature Summary

• Quad-channel architecture with 16-bit resolution and ±4 LSB maximum INL
• Integrated 2.5 V reference with low drift (2 ppm/°C typical)
• I²C compatible serial interface supporting up to 400 kHz clock rates
• Power-on reset ensures outputs initialize to zero or mid-scale

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 '-2' against official documentation to confirm if it denotes a distinct revision or packaging variant. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region.

Selection Notes

Select this component when multiple isolated analog outputs are required within a space-constrained design. Ensure the system logic levels are compatible with the 1.8 V interface requirements and that the 2.7 V to 5.5 V supply range aligns with the target power architecture.

Part Context

This part belongs to the AD567xR nanoDAC+ family, which provides multi-channel solutions for precision applications. The 'RL7' suffix indicates reel packaging for automated surface-mount assembly processes.

Replacement Considerations

Cross-reference with other members of the AD567xR family, such as the AD5676R or AD5678R, depending on whether channel count or resolution adjustments are necessary.
