AD5763CSUZ-REEL7

Overview

The AD5763CSUZ-REEL7 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 a 2.7 V to 5.25 V digital supply. The device provides bipolar voltage outputs with a nominal full-scale range of ±4.096 V, configurable via coarse gain registers. Key performance metrics include a maximum integral nonlinearity (INL) of ±1 LSB, a settling time of 10 μs, and an output noise spectral density of 70 nV/√Hz. It features integrated reference buffers, programmable short-circuit protection, and a die temperature sensor.

Feature Summary

• Dual-channel 16-bit resolution with guaranteed monotonicity and ±1 LSB INL/DNL errors
• Integrated reference buffers and output amplifiers supporting ±4.096 V, ±4.201 V, or ±4.311 V ranges
• 30 MHz SPI-compatible serial interface with double buffering for simultaneous channel updates
• On-chip die temperature sensor and programmable digital offset/gain adjustment per channel

Applications

• Industrial automation systems
• Open-loop and closed-loop servo control
• Process control applications
• High accuracy instrumentation
• Automatic test equipment

Procurement Notes

Verify the complete part number including the REEL7 suffix to confirm tape-and-reel packaging containing 500 units. Ensure the design supports the required ±5 V analog power rails and 2.7 V to 5.25 V digital logic levels. Confirm that the TQFP-32 package thermal management meets the system's dissipation requirements.

Selection Notes

Select this component when dual-channel high-precision conversion is required within a ±5 V supply environment. The AD5763 is suitable for applications demanding low noise and fast settling times. Consider the AD5764 or AD5765 if quad-channel configurations are needed instead of dual channels.

Part Context

The AD5763 belongs to the AD576x family of high-accuracy DACs manufactured using iCMOS process technology. It shares architectural similarities with the AD5764 and AD5765 but differs in channel count and output voltage ranges. The CSUZ suffix indicates the commercial temperature grade (-40°C to +105°C) and the TQFP-32 package type.

Replacement Considerations

The AD5764 and AD5765 are related devices offering quad-channel configurations. Direct pin-for-pin replacement is not possible due to different pin counts and functionalities. System redesign is required when transitioning between these variants.
