DAC7724NB/750G4

Digital To Analog Converters Overview

The DAC7724NB/750G4 is a 12-bit quad voltage output digital-to-analog converter manufactured by Texas Instruments. It features four independent channels with an R-2R resistor string architecture, delivering buffered analog outputs. The device operates on dual power supplies ranging from ±14.25 V to ±15.75 V for the analog section and a 5 V supply for the digital interface. It supports parallel data input and achieves a settling time of 10 µs at a sampling rate of 100 kS/s. The component is housed in a 28-pin PLCC package and functions within a temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Four independent 12-bit channels provide simultaneous voltage output capabilities.
• Integrated voltage buffers eliminate the need for external amplification.
• Parallel interface allows for high-speed data transfer up to 100 kS/s.
• Built-in reset function ensures outputs return to mid-scale upon initialization.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Programmable logic controller (PLC) analog output modules
• Test and measurement equipment calibration sources

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and lead-free construction as per Texas Instruments standards. Confirm the PLCC-28 package availability against current manufacturing status, as older variants may be obsolete. Ensure the supplier provides valid traceability documentation for the G4 designation to guarantee material composition matches datasheet specifications.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel solution with parallel interface is required. Compare INL and DNL specifications against system accuracy needs; the standard DAC7724NB offers ±2 LSB INL while the B-grade variant provides ±1 LSB. Verify that the 10 µs settling time meets the dynamic response requirements of the target application circuit.

Digital To Analog Converters Part Context

This part belongs to the DAC7724 family of 12-bit quad DACs. It shares architectural similarities with the DAC7724U and DAC7724N but utilizes a plastic leaded chip carrier package. The G4 suffix typically denotes environmental compliance modifications within the same functional family, maintaining pin compatibility with previous non-G4 versions.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible replacements include the DAC7724NB and DAC7724N. For serial interface alternatives, consider the DAC7614 or DAC7714 series, though these require different control logic. Verify thermal performance and package dimensions when substituting with SOIC-based variants like the DAC7724U.
