AD5764CSUZ-REEL7

Overview

The AD5764CSUZ-REEL7 is a quad, 16-bit digital-to-analog converter (DAC) featuring serial input and bipolar voltage outputs. 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 guarantees monotonicity with an integral nonlinearity (INL) of ±1 LSB maximum and differential nonlinearity (DNL) of ±1 LSB maximum. Key performance metrics include a settling time of 10 μs maximum, low noise of 60 nV/√Hz, and a serial interface supporting clock rates up to 30 MHz. It incorporates integrated reference buffers, programmable short-circuit protection, and digital offset/gain adjust registers for each channel.

Feature Summary

• Quad 16-bit resolution with ±1 LSB INL/DNL accuracy
• Bipolar voltage output with programmable ranges (±10 V, ±10.2564 V, or ±10.5263 V)
• Serial interface compatible with DSP and microcontrollers (up to 30 MHz)
• Integrated reference buffers and proprietary power-up/power-down control

Applications

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

Procurement Notes

Verify the C grade accuracy specifications against application requirements, as this variant offers ±1 LSB INL/DNL compared to higher error grades in the family. Confirm that the reel packaging format aligns with automated assembly capabilities. Ensure the operating temperature range of −40°C to +85°C meets environmental constraints. Check for moisture sensitivity handling requirements during storage and reflow soldering processes.

Selection Notes

Select the AD5764CSUZ-REEL7 when high precision (±1 LSB INL) and simultaneous updating via LDAC are required. Choose this part over the AD5764R if an external reference is preferred or already available in the system design. Consider the 32-lead TQFP package dimensions for PCB layout constraints. Verify that the digital logic supply (DVCC) matches the host controller voltage levels within the 2.7 V to 5.25 V range.

Part Context

The AD5764 series utilizes iCMOS process technology to achieve high performance at elevated supply voltages. This component belongs to a family of quad DACs designed for industrial applications requiring high accuracy and speed. The CSUZ suffix indicates a specific grade and tape-and-reel packaging configuration within the broader AD5764 product line.

Replacement Considerations

The AD5764R is a related device offering an internal voltage reference instead of external inputs. For lower resolution needs, the AD5744R provides a 14-bit alternative with an internal reference. The AD5754 and AD5754R offer unipolar/bipolar options with internal references.
