AD5763CSUZ

Overview

The AD5763CSUZ is a dual, 16-bit serial input digital-to-analog converter (DAC) from Analog Devices. It operates on ±4.75 V to ±5.25 V analog supplies and 2.7 V to 5.25 V digital supply. The device features integrated output amplifiers with a nominal full-scale range of ±4.096 V, programmable up to ±4.311 V. Key performance metrics include ±1 LSB maximum INL and DNL errors, 10 μs maximum settling time, and 70 nV/√Hz output noise spectral density. It utilizes a 30 MHz SPI-compatible serial interface and includes digital offset/gain adjustment registers per channel.

Feature Summary

• Dual-channel 16-bit resolution with guaranteed monotonicity
• Integrated reference buffers and output amplifiers
• Programmable short-circuit protection via external resistor
• On-chip die temperature sensor with 3 mV/°C scale factor

Applications

• Industrial automation systems
• Open-loop and closed-loop servo control
• Process control instrumentation
• High accuracy data acquisition systems

Procurement Notes

Verify the complete part number including suffixes such as CSUZ for package type and REEL7 for tape-and-reel quantity when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor specifications prior to procurement.

Selection Notes

Select this component for applications requiring high precision bipolar voltage outputs. Ensure the system provides stable ±5 V analog supplies and a compatible 2.7 V to 5.25 V digital logic level. Consider the need for an external 2.048 V reference source to achieve specified accuracy levels.

Part Context

The AD5763 belongs to the AD576x family of high-accuracy DACs. Related devices include the AD5764 (quad, ±10 V output) and AD5765 (quad, ±5 V output). These parts share similar serial interface protocols and architectural features but differ in channel count and output voltage ranges.

Replacement Considerations

Direct pin-compatible replacements within the same series include the AD5764 and AD5765, though these are quad-channel devices. Verify that the increased channel count does not impact board space or power budget constraints before substitution.
