AD5764RBSUZ

Overview

The AD5764RBSUZ is a quad, 16-bit serial input digital-to-analog converter (DAC) from Analog Devices Inc. It operates with analog supply voltages ranging from ±11.4 V to ±16.5 V and a digital supply of 2.7 V to 5.25 V. The device features integrated output amplifiers, reference buffers, and an internal 5 V reference with a maximum temperature coefficient of 10 ppm/°C. Key performance metrics include a maximum settling time of 10 μs, ±1 LSB maximum INL error for C Grade, and low noise of 60 nV/√Hz. It supports simultaneous updating via LDAC and includes programmable short-circuit protection and a die temperature sensor.

Feature Summary

• Quad 16-bit resolution with ±1 LSB max INL (C Grade) and ±1 LSB max DNL
• Integrated 5 V reference buffer with 10 ppm/°C max temperature coefficient
• Serial interface compatible with DSP/microcontrollers, supporting up to 30 MHz clock rates
• Programmable output range: ±10 V, ±10.2564 V, or ±10.5263 V

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 INL specifications differ between grades. Confirm that the 32-lead TQFP package is suitable for your PCB layout constraints. Ensure power supply rails match the ±11.4 V to ±16.5 V requirement for proper operation.

Selection Notes

Select the AD5764RBSUZ when high accuracy and bipolar voltage outputs are needed in a compact quad configuration. Choose C Grade if tighter linearity specifications (±1 LSB INL) are critical. Consider the integrated reference buffers if external precision references are not available or desired to simplify design.

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. This technology allows for reduced power consumption and package size while maintaining high AC and DC performance.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. Verify compatibility with existing system interfaces and power supplies before considering alternative components.
