AD5674RBCPZ-1-RL7

Overview

The AD5674RBCPZ-1-RL7 is a 16-channel, 12-bit buffered voltage output digital-to-analog converter (DAC) from Analog Devices. It features an internal 2.5 V reference with a typical temperature coefficient of 2 ppm/°C and supports SPI interfaces up to 50 MHz. The device operates on a single supply ranging from 2.7 V to 5.5 V and includes a user-selectable gain pin for full-scale outputs of 2.5 V or 5 V. Packaged in a 28-lead LFCSP, it incorporates power-on reset logic and low-power shutdown modes.

Feature Summary

• 16 channels with 12-bit resolution and ±1 LSB maximum INL
• Internal 2.5 V reference with 2 ppm/°C temperature coefficient
• 50 MHz SPI interface with readback and daisy-chain capabilities
• User-selectable gain (×1 or ×2) via GAIN pin

Applications

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

Procurement Notes

Verify the specific suffix '-1' against official documentation to confirm the exact power-up state configuration. Confirm package type and RoHS compliance status through authorized distributors. Ensure ESD handling protocols are followed during assembly due to moisture sensitivity classification.

Selection Notes

Select this component for applications requiring high channel density within a compact footprint. Verify that the 12-bit resolution meets system accuracy requirements compared to the 16-bit AD5679 variant. Check if the internal reference drift specifications align with thermal stability needs across the -40°C to +125°C operating range.

Part Context

This part belongs to the nanoDAC+ family, designed for multi-channel precision conversion. It shares architectural similarities with the AD5679 but offers lower bit resolution. The device integrates buffer amplifiers and reference circuitry to simplify board layout and reduce external component count.

Replacement Considerations

The AD5674RBCPZ-RL7 serves as a direct replacement for the non-R version (AD5674BCPZ-RL7) regarding functionality, differing primarily in lead-free packaging. Cross-model substitution with the AD5679 requires verification of resolution differences.
