DAC7724UB

Digital To Analog Converters Overview

The DAC7724UB is a quad-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It utilizes an R-2R resistor string architecture to provide buffered voltage outputs with a sampling rate of 100 kS/s and a settling time of 10 µs. The device features a parallel interface and operates on dual analog supply voltages ranging from ±14.25 V to ±15.75 V, alongside a 5 V digital supply. Key performance metrics include a gain error of 0.05% FSR, differential nonlinearity (DNL) of ±1 LSB, and integral nonlinearity (INL) of ±1 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.
• Supports reset-to-mid-scale functionality to ensure defined output states upon initialization.
• Employs an R-2R architecture to achieve high linearity with minimal differential and integral nonlinearity errors.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Programmable power supplies and test equipment
• Data acquisition systems needing precise analog reference outputs

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'UB' against the manufacturer's current datasheet to confirm pinout compatibility and packaging details. Ensure that the required operating temperature range and supply voltage specifications align with the target application environment before finalizing procurement decisions.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel solution with parallel interface and high accuracy is required. Compare against the serial-interface DAC7714UB if pin count reduction is necessary, noting the difference in data throughput and interface complexity between parallel and serial architectures.

Digital To Analog Converters Part Context

This part belongs to the DAC7724 family of precision digital-to-analog converters. It serves as the surface-mount variant of the through-hole DAC7724N, which has been marked as obsolete. The UB designation indicates the specific SOIC-28 package configuration used for automated assembly processes.

Digital To Analog Converters Replacement Considerations

The DAC7724N is an obsolete equivalent offering identical electrical parameters but in a PLCC package. For new designs, verify if the DAC7724UB/1K bulk packaging option is available instead of the tube format for cost efficiency.
