AD5724RBREZ-REEL7

Overview

The AD5724RBREZ-REEL7 is a quad, 12-bit serial input digital-to-analog converter (DAC) from Analog Devices. It features an integrated +2.5 V reference with ±5 ppm/°C maximum temperature coefficient and output buffers. The device supports single (+4.5 V to +16.5 V) or dual (±4.5 V to ±16.5 V) supplies, offering software-selectable unipolar/bipolar output ranges including ±10 V. Key specifications include a typical settling time of 10 µs, INL error of ±1 LSB maximum, and DNL error of ±1 LSB maximum. It utilizes a DSP/microcontroller-compatible serial interface operating up to 30 MHz.

Feature Summary

• Quad channel architecture with 12-bit resolution
• Integrated precision reference (±5 ppm/°C) and output buffers
• Software programmable output range: +5 V, +10 V, +10.8 V, ±5 V, ±10 V, ±10.8 V
• Simultaneous updating via LDAC pin

Applications

• Industrial automation systems
• Closed-loop servo control applications
• Process control instrumentation
• Automotive test and measurement equipment
• Programmable logic controllers (PLCs)

Procurement Notes

Verify the REEL7 suffix indicates tape-and-reel packaging when sourcing components. Confirm that the specific part number corresponds to the 'R' variant which includes the internal reference, distinguishing it from the standard AD5724 series. Ensure compatibility with the required supply voltage range and thermal management for the 24-lead TSSOP package.

Selection Notes

Select this component for applications requiring four independent 12-bit voltage outputs with high accuracy. The integrated reference eliminates the need for external precision voltage sources. Consider the 10 µs settling time and ±1 LSB INL for precision requirements. Verify that the serial interface timing meets the microcontroller or DSP clock speed constraints.

Part Context

This part belongs to the AD5724R/AD5734R/AD5754R family of complete, serial input DACs. The 'R' designation signifies the inclusion of an on-chip reference, unlike the non-R versions. The AD5724R specifically provides 12-bit resolution, whereas the AD5734R offers 14 bits and the AD5754R offers 16 bits. All share the same pinout and functional block diagram.

Replacement Considerations

The AD5724AREZ is a parameter-equivalent alternative within the same family but lacks the internal reference. When substituting, an external 2.5 V reference source must be provided to the REFIN pin. Verify that the external reference meets the noise and drift specifications previously handled by the integrated reference.
