Overview
The AD5764RCSUZ-REEL7 is a quad, 16-bit digital-to-analog converter (DAC) from Analog Devices. It features serial input and bipolar voltage outputs with a nominal full-scale range of ±10 V. The device operates on supply voltages of ±11.4 V to ±16.5 V for analog circuits and 2.7 V to 5.25 V for digital logic. Key performance metrics include a maximum integral nonlinearity (INL) error of ±1 LSB for the C-grade device, a settling time of 10 μs maximum, and low noise spectral density of 60 nV/√Hz. It incorporates integrated output amplifiers, reference buffers, and an internal 5 V reference.
Feature Summary
- Quad 16-bit resolution with guaranteed monotonicity and ±1 LSB INL/DNL (C Grade)
- Integrated 5 V reference buffer with 10 ppm/°C temperature coefficient
- On-chip die temperature sensor providing 5 mV/°C scale factor
- Programmable short-circuit protection via external resistor
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 your application, as accuracy specifications differ between grades. Confirm that the REEL7 packaging format meets your automated assembly requirements. Ensure the design accounts for the industrial temperature range of −40°C to +85°C.
Selection Notes
Select the C grade if strict ±1 LSB INL and DNL limits are necessary for high-precision applications. The B grade offers ±2 LSB INL. Consider the internal reference's 10 ppm/°C drift when designing for wide temperature variations, or use an external precision reference connected to REFAB/REFCD pins for enhanced stability.
Part Context
This component belongs to the AD5764 family of high-performance DACs. It utilizes iCMOS technology to support higher voltage levels while maintaining low power consumption. The AD5764R variant specifically includes an internal reference and temperature sensor, distinguishing it from variants requiring external references.
Replacement Considerations
The AD5764CSUZ is a direct pin-compatible alternative within the same family. Note that the standard AD5764 lacks the internal reference found in the AD5764R, requiring external components for equivalent functionality.
