DAC7724UB/1K

Digital To Analog Converters Overview

The DAC7724UB/1K is a quad-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features an R-2R resistor string architecture with buffered voltage outputs and a parallel interface. The device operates on dual analog supply voltages of ±15 V and a digital supply of 5 V. Key performance metrics include a sampling rate of 100 kS/s, a settling time of 10 µs, and power consumption of 45 mW. Nonlinearity specifications are ±1 LSB for both DNL and INL, with a gain error of 0.05% FSR. It functions within a temperature range of -40°C to +85°C and is housed in a 28-pin SOIC package.

Digital To Analog Converters Feature Summary

• Quad-channel configuration providing four independent 12-bit DACs in a single package.
• Integrated output buffers deliver voltage signals directly without external amplification.
• Parallel interface supports high-speed data transfer for synchronous system applications.
• Internal reset mechanism allows outputs to return to mid-scale upon initialization.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Programmable power supplies and test equipment
• Data acquisition systems with analog output capabilities

Digital To Analog Converters Procurement Notes

Verify the specific suffix '1K' against the manufacturer's official documentation to confirm packaging details, as standard datasheets may list tube packaging for the base part number. Ensure compatibility with the required operating temperature range and supply voltages before integration into the design.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel solution with parallel interface and buffered voltage outputs is required. Compare against the serial-interface DAC7715 if pin count reduction is necessary, or consider the DAC7725 for current-output applications. Verify that the 10 µs settling time meets the system's bandwidth requirements.

Digital To Analog Converters Part Context

This part belongs to the DAC7724 family of precision digital-to-analog converters. It shares architectural similarities with the DAC7725 but differs in output type. The device is designed for general-purpose analog signal generation in industrial environments where moderate speed and high accuracy are balanced.

Digital To Analog Converters Replacement Considerations

The DAC7724N is a legacy PLCC variant of the same functional device. For surface-mount replacements, verify pinout compatibility between the SOIC-28 package and existing PCB footprints. No direct modern equivalent is listed in the provided source material.
