DAC7724N

Digital To Analog Converters Overview

The DAC7724N is a low-power, four-channel, 12-bit parallel voltage-output digital-to-analog converter manufactured by Burr-Brown. It operates on a single +15V or dual ±15V supply, with typical power consumption of 45 mW and maximum of 250 mW. The device features a 28-PLCC package, measuring 11.58 x 11.58 x 4.06 mm, and supports an operating temperature range from -40°C to +85°C. Key electrical parameters include a 10µs settling time, ±1 LSB DNL/INL, and TTL-CMOS logic compatibility. Output ranges are +10V for single-supply and ±10V for dual-supply configurations.

Digital To Analog Converters Feature Summary

• Built-in readback circuitry allowing direct access to internal register contents for diagnostics
• R-2R resistor ladder architecture ensuring high linearity and precision conversion

Digital To Analog Converters Applications

• Automotive control systems requiring multi-channel signal processing
• Industrial process control instrumentation
• Communication equipment signal conditioning

Digital To Analog Converters Procurement Notes

Verify the specific manufacturer designation, as Texas Instruments acquired Burr-Brown. Confirm the exact suffix (e.g., N vs NB) determines the package type and thermal characteristics. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing standards. Check for active lifecycle status versus obsolescence notices before finalizing procurement plans.

Digital To Analog Converters Selection Notes

Select this component when multiple isolated voltage outputs are required in a compact form factor. The parallel interface suits applications needing high-speed data throughput without serial protocol overhead. Consider the ±1 LSB linearity for precision tasks. Evaluate power dissipation limits within the enclosure design, especially under worst-case thermal conditions.

Digital To Analog Converters Part Context

This part belongs to the Burr-Brown family of precision data converters, now integrated into Texas Instruments' portfolio. It serves as a legacy solution for systems designed around parallel bus architectures. The device complements other Burr-Brown ADCs like the ADS7844N in mixed-signal acquisition chains.

Digital To Analog Converters Replacement Considerations

The DAC7725N is a related quad-channel 12-bit DAC but exhibits different non-linearity specifications (+/- 2 LSB INL). Verify pinout compatibility and software register mapping differences before substituting. No direct drop-in replacements are confirmed in public documentation.
