DAC7631EG4

Digital To Analog Converters Overview

The DAC7631EG4 is a single-channel, 16-bit digital-to-analog converter manufactured by Texas Instruments. It utilizes an R-2R resistor string architecture to provide voltage output with a sampling rate of 93 kS/s and a settling time of 10 µs. The device operates on a single 5 V supply or dual supplies ranging from ±4.75 V to ±15.75 V. Key electrical specifications include a maximum integral nonlinearity (INL) of ±3 LSB and a gain error of 0.08% FSR. It features a serial interface for data input and supports reset to mid-scale functionality. The component is housed in a 20-pin SSOP package and operates within a temperature range of -40°C to +85°C.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's current datasheet to confirm lead-free compliance status and exact pinout configuration. Ensure the ordering part number matches the required package variant and temperature grade. Cross-reference with official distributor catalogs to confirm availability and authenticity before procurement.

Digital To Analog Converters Selection Notes

Select this component when a single-channel 16-bit resolution is required with low power constraints. Compare against the DAC7631E for identical performance characteristics. Consider the DAC7731E if buffered output or higher speed is needed, noting the difference in pin count and internal reference integration. Verify supply voltage requirements match the application's power rails.

Digital To Analog Converters Part Context

The DAC7631EG4 belongs to the DAC7631 family of serial input digital-to-analog converters. It shares architectural similarities with other Burr-Brown derived DACs from Texas Instruments. The 'G4' suffix typically indicates lead-free packaging compliant with RoHS standards, distinguishing it from older non-compliant variants while maintaining functional equivalence.

Digital To Analog Converters Replacement Considerations

Direct substitutes include the DAC7631E and DAC7631EB/1K. These parts share the same core functionality and pinout. Verify that any replacement maintains the required 16-bit resolution and serial interface compatibility.
