DAC7612UG4

Digital To Analog Converters Overview

The DAC7612UG4 is a dual-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It operates on a single +5V supply and features an R-2R architecture with rail-to-rail buffered voltage outputs. The device integrates a 2.435V internal reference, serial input shift register, and two DACs. Key electrical parameters include a sampling rate of 130 ksps, a settling time of 7 µs to 1 LSB, and a maximum power consumption of 3.5 mW. Differential nonlinearity (DNL) and integral nonlinearity (INL) are specified at ±0.25 LSB. It functions within an industrial temperature range of -40°C to +85°C and is housed in an 8-pin SOIC package.

Digital To Analog Converters Feature Summary

• Data acquisition systems utilizing serial communication interfaces

Digital To Analog Converters Procurement Notes

Verify the G4 suffix indicates lead-free compliance and RoHS standards when sourcing. Confirm the specific package variant matches the required PCB footprint. Ensure the operating environment stays within the specified -40°C to +85°C range. Check for moisture sensitivity level requirements during storage and handling. Validate that the single 5V supply aligns with system power constraints.

Digital To Analog Converters Selection Notes

Select this component for applications requiring dual isolated voltage outputs with high accuracy. The integrated reference eliminates external component needs, simplifying board layout. Consider the 7 µs settling time for real-time control loops. The serial interface reduces pin count compared to parallel alternatives. Verify compatibility with available clock speeds for the 130 ksps update rate.

Digital To Analog Converters Part Context

The DAC7612UG4 belongs to the DAC7612 family of precision dual DACs. The 'G4' suffix typically denotes a lead-free and RoHS-compliant version of the standard DAC7612U. It shares core specifications with the base model but adheres to stricter environmental manufacturing standards. This part serves as a direct replacement for earlier non-G4 variants in existing designs requiring updated compliance.

Digital To Analog Converters Replacement Considerations

The DAC7612U is the primary equivalent part number. The DAC7612UB offers identical functionality with different packaging options. Verify pinout compatibility before substitution. Ensure thermal performance remains adequate for the new variant.
