DAC7731E

Digital To Analog Converters Overview

The DAC7731E is a single-channel, 16-bit voltage-output digital-to-analog converter manufactured by Texas Instruments. It features an internal +10V reference and utilizes a 3-wire SPI serial interface for data input. The device employs an R-2R resistor ladder architecture and provides buffered voltage outputs. Key electrical specifications include a sampling rate of 172 kS/s, a settling time of 3 µs, and a maximum power dissipation of 150 mW. It operates within an analog supply range of ±4.75 V to ±15.75 V and a digital supply of 5 V. The component supports operation from -40°C to +85°C and is housed in an SSOP-24 package.

Digital To Analog Converters Feature Summary

• Integrates a precision internal +10V reference source to simplify system design.
• Provides buffered voltage output capability for direct drive applications.
• Supports standard 3-wire synchronous serial communication protocols.

Digital To Analog Converters Applications

Digital To Analog Converters Procurement Notes

Verify the specific suffix designation when ordering, as packaging formats vary between tube and reel configurations across the DAC7731 family. Confirm that the selected variant matches the required operating temperature range and pinout compatibility for the target PCB layout. Ensure compliance with RoHS directives if applicable to the end product requirements.

Digital To Analog Converters Selection Notes

Select this component for applications requiring a single-channel 16-bit resolution with integrated reference capabilities. Compare differential nonlinearity and integral nonlinearity specifications against system accuracy requirements. Consider the SSOP-24 package dimensions and thermal characteristics during the mechanical design phase to ensure adequate heat dissipation under maximum load conditions.

Digital To Analog Converters Part Context

This part belongs to the DAC7731 series of monolithic digital-to-analog converters. The series includes variants such as the DAC7731EC and DAC7731E/1K, which share core functional specifications but may differ in packaging or minor electrical tolerances. The DAC7731E specifically denotes the standard commercial grade version available in tube packaging.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same family include the DAC7731EC and DAC7731E/1K. Verify pin compatibility and electrical parameter alignment before substitution. Other Texas Instruments 16-bit serial DACs may require significant circuit redesign due to interface or reference differences.
