AD5764RBSUZ-REEL7

Overview

The AD5764RBSUZ-REEL7 is a quad, 16-bit serial input, bipolar voltage output digital-to-analog converter (DAC) from Analog Devices. It operates from supply voltages of ±11.4 V to ±16.5 V with a nominal full-scale output range of ±10 V. The device features integrated output amplifiers, reference buffers, and proprietary power-up/power-down control circuitry. Key specifications include a maximum settling time of 10 μs, ±1 LSB maximum INL error for the C grade, and low noise of 60 nV/√Hz. It utilizes an iCMOS process technology and supports a DSP/microcontroller-compatible serial interface operating at clock rates up to 30 MHz.

Feature Summary

• Quad 16-bit DAC with programmable output ranges of ±10 V, ±10.2564 V, or ±10.5263 V
• Integrated 5 V reference with 10 ppm/°C maximum temperature coefficient
• On-chip die temperature sensor and digital I/O port (D0, D1)
• Programmable short-circuit protection via external resistor
• Simultaneous updating of all channels via LDAC pin

Applications

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

Procurement Notes

Verify the specific grade (B or C) required for your application, as accuracy parameters such as INL differ between grades. Confirm that the REEL7 suffix indicates tape and reel packaging suitable for automated assembly. Ensure the design accommodates the required analog supply voltages (±11.4 V to ±16.5 V) and digital logic levels (2.7 V to 5.25 V). Check for moisture sensitivity handling requirements during storage and reflow soldering.

Selection Notes

Select the C grade if guaranteed monotonicity and ±1 LSB maximum INL are critical; the B grade offers ±2 LSB INL. Consider the internal 5 V reference if external precision references are not needed, noting that external reference inputs (REFAB, REFCD) can also be used for custom output ranges. Evaluate the need for the on-chip temperature sensor and digital I/O pins to reduce external component count. Ensure the serial interface timing meets the microcontroller or DSP clock speed requirements.

Part Context

The AD5764R is part of the AD5764 family of high-accuracy, serial input DACs. It shares architectural similarities with other iCMOS devices but is distinct in its dual-supply operation and integrated reference buffers. The REEL7 designation specifically refers to the reel packaging format, distinguishing it from tray-packaged variants like the AD5764CSUZ. This component is designed for industrial instrumentation applications requiring high voltage swings and precise analog control.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should verify compatibility with existing system constraints if considering alternative quad-channel DACs.
