AD5764RCSUZ

Overview

The AD5764RCSUZ is a quad, 16-bit digital-to-analog converter (DAC) featuring bipolar voltage outputs. It operates from analog supply voltages of ±11.4 V to ±16.5 V and a digital supply of 2.7 V to 5.25 V. The device provides a nominal full-scale output range of ±10 V with programmable ranges up to ±10.5263 V. Key performance metrics include a maximum settling time of 10 μs, integral nonlinearity (INL) of ±1 LSB for the C grade, and differential nonlinearity (DNL) of ±1 LSB. It incorporates an internal 5 V reference with a temperature coefficient of 10 ppm/°C max, integrated output amplifiers, and a serial interface compatible with DSP and microcontrollers.

Feature Summary

• Quad 16-bit resolution with ±1 LSB INL/DNL accuracy
• Integrated 5 V reference buffer and output amplifiers
• Serial interface supporting up to 30 MHz clock rates
• On-chip die temperature sensor and digital I/O port

Applications

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

Procurement Notes

Verify the specific grade (B or C) required for INL specifications, as the datasheet lists ±2 LSB for B grade and ±1 LSB for C grade. Confirm the package type is 32-lead TQFP. Ensure the design accounts for the industrial temperature range of −40°C to +85°C. Check power supply requirements against the specified ±11.4 V to ±16.5 V analog and 2.7 V to 5.25 V digital rails.

Selection Notes

Select the AD5764RCSUZ when four independent 16-bit channels are needed with high accuracy and fast settling times. The C grade is suitable for applications requiring guaranteed ±1 LSB INL. Consider the internal reference if external precision references are not desired. The iCMOS process allows for operation at higher voltage levels while maintaining low power consumption compared to older technologies.

Part Context

The AD5764R is part of Analog Devices' iCMOS technology platform, designed for industrial and instrumentation applications requiring high-performance analog ICs at higher voltage levels. It belongs to the AD5764 family, which includes variants like the AD5764 (non-R) and other channel counts such as the AD5762 (dual) and AD5763 (dual). The 'R' suffix typically indicates a reel packaging option, while 'CSUZ' denotes the specific commercial grade and TQFP package.

Replacement Considerations

For direct pin-compatible replacements within the same family, consider the AD5764ASUZ or AD5764CSUZ. Note that the AD5764 (without the R suffix) may have different packaging or minor specification variations. For dual-channel applications, the AD5762R or AD5763R series offers similar architecture but with two channels instead of four.
