DAC7725UBG4

Digital To Analog Converters Overview

The DAC7725UBG4 is a quad-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It utilizes an R-2R resistor string architecture and features a parallel digital interface for data input. The device provides buffered voltage outputs with a typical settling time of 10µs. It operates on dual analog supply voltages ranging from ±14.25V to ±15.75V and a single 5V digital supply. Key performance metrics include a maximum integral nonlinearity (INL) of ±2 LSB and differential nonlinearity (DNL) of ±1 LSB. The component is housed in a 28-pin SOIC package and supports an operating temperature range from -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Four independent buffered voltage output channels integrated into a single package
• Parallel interface compatibility for straightforward digital control
• External voltage reference capability for flexible system design
• Reset function to mid-scale output state

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Programmable power supplies with multiple output rails

• Test and measurement equipment needing precise analog waveform synthesis

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'G4' indicates lead-free packaging compliant with RoHS standards. Confirm the package type is SOIC-28 and check for moisture sensitivity level requirements during storage. Ensure the supplier provides valid traceability documentation for the Texas Instruments manufacturing origin.

Digital To Analog Converters Selection Notes

Select this component when four synchronized 12-bit outputs are required with a parallel interface. Compare against the DAC7724 if serial communication is preferred or if different pinout constraints exist. Verify that the external reference requirement aligns with the system's available voltage references and noise specifications.

Digital To Analog Converters Part Context

This part belongs to the DAC7724/7725 family of high-speed, low-power quad DACs. The DAC7725 variant specifically distinguishes itself through its parallel interface configuration, whereas other family members may offer serial options. The G4 suffix denotes environmental compliance, indicating a lead-free finish compared to earlier standard versions.

Digital To Analog Converters Replacement Considerations

The DAC7725N serves as a PLCC package alternative within the same functional family. For serial interface requirements, the DAC7724 series offers compatible electrical characteristics with different connectivity. Verify pin compatibility and software register settings when substituting these parts.
