DAC7724NB

Digital To Analog Converters Overview

The DAC7724NB is a low-power, four-channel, 12-bit parallel voltage-output digital-to-analog converter manufactured by Texas Instruments under the Burr-Brown brand. It utilizes an R-2R architecture and operates on single +15V or dual ±15V supplies. The device features buffered voltage outputs with a typical power consumption of 45 mW and a maximum of 250 mW. Key electrical parameters include a settling time of 10 µs, differential nonlinearity (DNL) of ±1 LSB, and integral nonlinearity (INL) of ±1 LSB. It supports TTL-CMOS logic levels and direct binary data formats. The component is housed in a 28-pin PLCC package measuring 11.58 x 11.58 x 4.06 mm and functions within a temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Dual-buffered data input structure allows for synchronous updates across all channels.
• Built-in readback circuit enables retrieval of internal register contents.
• Asynchronous reset function clears registers to mid-scale output levels.

Digital To Analog Converters Applications

• Industrial control systems requiring multi-channel signal generation
• Automotive electronic modules needing reliable analog conversion
• Communication equipment utilizing parallel interface data processing

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'NB' against the manufacturer's current datasheet to confirm the PLCC-28 package variant. Ensure the supply chain source provides documentation confirming the active status and original Burr-Brown/Texas Instruments lineage. Cross-reference the part number with official distributor catalogs to validate authenticity and avoid counterfeit components.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel, 12-bit resolution is required with parallel interfacing capabilities. It is suitable for designs demanding low power consumption alongside high accuracy metrics such as ±1 LSB linearity. Consider the PLCC package constraints if surface-mount technology is not feasible or if legacy socket-based designs are being maintained.

Digital To Analog Converters Part Context

This device belongs to the DAC7724 series, originally developed by Burr-Brown Corporation before its acquisition by Texas Instruments. The series represents a transition period where Burr-Brown products were integrated into TI's portfolio while retaining their distinct branding and performance characteristics. It serves as a bridge between older Burr-Brown designs and modern TI manufacturing standards.

Digital To Analog Converters Replacement Considerations

The DAC7724UB offers identical functional specifications but utilizes a SOIC-28 surface-mount package instead of the PLCC form factor. Designers requiring leadless or smaller footprint solutions may consider this alternative, provided the PCB layout accommodates the different pin configuration and thermal requirements of the SOIC package.
