DAC7724U

Digital To Analog Converters Overview

The DAC7724U 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 supports parallel data interfaces. 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 a power consumption of 45 mW. Nonlinearity specifications are defined by a maximum differential nonlinearity (DNL) of ±1 LSB and integral nonlinearity (INL) of ±2 LSB. 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

• Integrates four independent 12-bit DAC channels with internal buffering for direct drive capability.
• Utilizes an R-2R resistor string architecture to ensure stable conversion characteristics.
• Includes a reset function that forces all outputs to mid-scale upon initialization.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Programmable gain amplifier circuits
• Waveform generation equipment

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'U' indicates the SOIC-28 surface-mount package variant. Confirm RoHS compliance status through the manufacturer's current documentation. Check for active manufacturing status as older revisions may be obsolete. Ensure the digital interface voltage levels match the system logic requirements before integration.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel configuration with high accuracy is required. The 100 kS/s update rate suits moderate-speed applications. Compare against the DAC7725N if a PLCC package is preferred instead of SOIC. Verify that the ±15 V supply rails are available in the target design environment.

Digital To Analog Converters Part Context

This part belongs to the DAC7724 family, which provides quad-channel solutions. It shares architectural similarities with the DAC7725, differing primarily in the physical package type. The series is designed for general-purpose analog output applications where channel count and resolution balance are critical.

Digital To Analog Converters Replacement Considerations

The DAC7725N is a functional equivalent offering identical electrical specifications but utilizes a PLCC-28 package instead of SOIC-28. Verify pinout compatibility and thermal dissipation requirements when substituting between these package types.
