DAC7731EG4

Digital To Analog Converters Overview

The DAC7731EG4 is a single-channel, 16-bit digital-to-analog converter manufactured by Texas Instruments under the Burr-Brown brand. It features an R-2R architecture with a buffered voltage output and supports serial interfaces including 3-Wire and SPI. The device operates on a 5V digital supply and dual analog supplies ranging from +15V to -15.75V. Key electrical specifications include a settling time of 3 µs, differential nonlinearity of ±4 LSB, and integral nonlinearity of ±6 LSB. It functions within a temperature range of -40°C to +85°C and is housed in a 24-pin SSOP package.

Digital To Analog Converters Feature Summary

• Integrated internal reference providing a +10V output range
• Programmable reset function for mid-scale or zero scale initialization
• Serial data readback capability via SDO pin

Digital To Analog Converters Applications

• Industrial process control systems requiring precise voltage regulation
• Portable instrumentation utilizing low power consumption modes
• Data acquisition systems needing high-resolution analog outputs

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's current datasheet to confirm lead-free compliance and RoHS status. Ensure the ordering part number matches the exact package type and temperature grade required for the target application environment. Cross-reference with official distributor catalogs to confirm active status and availability.

Digital To Analog Converters Selection Notes

Select this component when a single-channel, high-resolution 16-bit output is required with integrated reference capabilities. Consider the 3µs settling time and ±6 LSB INL for applications demanding moderate speed and precision. Evaluate the SSOP-24 footprint constraints and verify that the serial interface timing meets the system clock requirements.

Digital To Analog Converters Part Context

The DAC7731EG4 belongs to the DAC7731 family of 16-bit voltage output digital-to-analog converters. This series is designed for applications requiring low power consumption and high accuracy. The EG4 designation typically indicates a lead-free, RoHS-compliant variant of the standard DAC7731E, maintaining identical electrical performance while adhering to environmental regulations.

Digital To Analog Converters Replacement Considerations

The DAC7731E is the direct functional equivalent. Verify if the G4 suffix denotes a specific packaging or environmental update rather than a functional change. Other compatible parts in the family include the DAC7731E/1K for reel packaging.
