DAC7734E

Digital To Analog Converters Overview

The DAC7734E is a 16-bit, quad-channel voltage-output digital-to-analog converter manufactured by Texas Instruments under the Burr-Brown brand. It features an R-2R architecture with serial input capability and buffered voltage outputs. The device operates on dual analog supply voltages of ±15 V and a digital supply of ±15 V. Key performance metrics include a settling time of 10 µs, a sampling rate of 89 kS/s, and power consumption of 50 mW. Differential and integral nonlinearity are specified at ±3 LSB, with a gain error of 0.05% FSR. It is housed in a 48-pin SSOP package and functions within a temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Quad-channel configuration providing four independent 16-bit digital-to-analog converters in a single package.
• Serial interface compatibility for simplified system integration and reduced pin count.
• Integrated reset function allowing outputs to return to mid-scale upon initialization.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Data acquisition systems utilizing serial communication protocols
• Test and measurement equipment needing precise voltage references

Digital To Analog Converters Procurement Notes

Verify the manufacturer designation as Texas Instruments, which acquired Burr Brown, when sourcing this component. Confirm the specific suffix 'E' indicates the extended temperature range variant (-40°C to +85°C). Ensure the package type matches the required SSOP-48 footprint for PCB layout compatibility. Check RoHS compliance status through official distributor documentation prior to procurement.

Digital To Analog Converters Selection Notes

Select the DAC7734E when a design requires four synchronized 16-bit channels with serial control. Compare against the DAC7731 if only a single channel is needed, noting differences in resolution and speed. Consider the DAC7744 if parallel input is preferred over serial interfaces. Evaluate power consumption requirements against the 50 mW specification to ensure thermal management fits the enclosure constraints.

Digital To Analog Converters Part Context

The DAC7734 belongs to the DAC773x family of high-performance digital-to-analog converters from Texas Instruments. This series integrates precision reference circuitry and output amplifiers. The DAC7734 specifically addresses applications demanding multiple isolated analog outputs controlled via a serial bus, offering a compact solution compared to discrete implementations.

Digital To Analog Converters Replacement Considerations

The DAC7734EBG4 is a lead-free version of the same functional device. The DAC7731 serves as a single-channel alternative within the same product family. Verify pinout compatibility before substituting with other quad-channel DACs from different manufacturers.
