AD5744RCSUZ-REEL7

Overview

The AD5744RCSUZ-REEL7 is a quad, 14-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It operates from supply voltages of ±11.4 V to ±16.5 V and provides bipolar voltage outputs with a nominal full-scale range of ±10 V. The device features integrated output amplifiers, reference buffers, and an on-chip 5 V reference with a maximum temperature coefficient of 10 ppm/°C. Key performance specifications include a maximum settling time of 10 μs, integral nonlinearity (INL) of ±1 LSB, and differential nonlinearity (DNL) of ±1 LSB. It utilizes a serial interface compatible with DSP and microcontroller standards, supporting clock rates up to 30 MHz.

Feature Summary

• Quad 14-bit resolution with guaranteed monotonicity and ±1 LSB INL/DNL errors
• Integrated 5 V reference buffer with 10 ppm/°C maximum temperature coefficient
• Programmable output ranges: ±10 V, ±10.2564 V, or ±10.5263 V
• Simultaneous updating via LDAC pin for synchronized multi-channel control

Applications

• Industrial automation systems
• Open-loop and closed-loop servo control
• Process control instrumentation
• Data acquisition systems
• Automatic test equipment

Procurement Notes

Verify the REEL7 suffix indicates tape-and-reel packaging when sourcing. Confirm the operating temperature range meets system requirements, as the device is specified for −40°C to +85°C. Ensure power supplies are within the ±11.4 V to ±16.5 V range for analog rails and 2.7 V to 5.25 V for digital logic. Check datasheet for ESD handling precautions during assembly.

Selection Notes

Select this component for applications requiring high accuracy and simultaneous multi-channel updates. The internal reference simplifies design by reducing external component count. Verify that the load capacitance does not exceed stability limits (200 pF unloaded, 1000 pF with 10 kΩ load). Consider the 32-lead TQFP package dimensions for PCB layout constraints.

Part Context

The AD5744R belongs to the iCMOS family, designed for industrial and instrumentation OEMs needing high-performance ICs at higher voltage levels. This technology allows operation at ±15 V supplies while maintaining low power consumption. The part number AD5744RCSUZ-REEL7 specifies the commercial grade version in a 32-TQFP package with reel packaging.
