AD5679RBCPZ-2-RL7

Overview

The AD5679RBCPZ-2-RL7 is a 16-channel, 16-bit buffered voltage output digital-to-analog converter (DAC) from Analog Devices. It integrates a 2.5 V internal reference with a typical temperature coefficient of 2 ppm/°C and features a user-selectable gain pin 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 zero-scale or midscale startup. It supports a 50 MHz SPI interface with readback capabilities and consumes 2 μA in power-down mode. Packaged in a 28-lead LFCSP.

Feature Summary

• 16 channels with ±4 LSB maximum integral nonlinearity (INL)
• Integrated 2.5 V reference with 2 ppm/°C temperature coefficient
• User-selectable gain of 1 or 2 via GAIN pin
• 50 MHz SPI interface with daisy-chain and readback support

Applications

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

Procurement Notes

Verify the suffix -2-RL7 against the manufacturer's ordering guide to confirm specific factory settings or packaging variations. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check current availability as distribution may be limited.

Selection Notes

Select this model for high-density applications requiring 16 channels in a compact 4 mm × 4 mm package. Ensure the required output span matches the GAIN pin configuration (2.5 V or 5 V). Verify that the 50 MHz SPI speed is compatible with the host microcontroller. Consider the 2 μA power-down current for low-power system designs.

Part Context

This component belongs to the nanoDAC+ family, which provides high channel density and integrated references. The AD5679R variant specifically includes the low-drift internal reference, distinguishing it from the standard AD5679 which requires an external reference. The -2 suffix typically denotes specific factory calibration or packaging options within the product line.

Replacement Considerations

The AD5679 (without R) is a functional substitute if an external reference is used. The AD5674R offers 12-bit resolution with similar packaging. Cross-reference the exact -2 suffix requirements with Analog Devices documentation before substitution.
