DAC70504RTER

Digital To Analog Converters Overview

The DAC70504RTER is a true 14-bit, four-channel digital-to-analog converter manufactured by Texas Instruments. It features an R-2R architecture with buffered voltage outputs and operates via an SPI interface. The device supports analog supply voltages from 2.7 V to 5.5 V and digital supplies from 1.7 V to 5.5 V. Key performance metrics include a settling time of 5 µs, differential nonlinearity (DNL) of ±1 LSB, integral nonlinearity (INL) of ±0.5 LSB, and gain error of 0.14% FSR. It functions within a temperature range of -40°C to +125°C in a WQFN-16 package.

Digital To Analog Converters Feature Summary

• Four independent channels providing simultaneous analog output generation
• Integrated reset function allowing return to mid-scale or zero scale upon power-on
• Compact surface-mount packaging designed for space-constrained applications

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Portable instrumentation utilizing low-power voltage reference outputs
• Automotive sensor simulation and testing equipment

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'RTER' against official datasheets to confirm tape-and-reel packaging and moisture sensitivity level. Ensure compatibility with standard SPI protocols and check for any regional regulatory compliance requirements such as RoHS status before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when four synchronized 14-bit outputs are required with high accuracy. Compare DNL and INL specifications against system noise floors. Verify that the 5 µs settling time meets the application's update rate requirements and that the WQFN-16 footprint fits the PCB layout constraints.

Digital To Analog Converters Part Context

This part belongs to the DACx0504 family, which includes variants with different resolutions and accuracy levels. It shares the same physical footprint and pinout with other members like the DAC60504 and DAC80504, facilitating design upgrades or downgrades without changing the board layout.

Digital To Analog Converters Replacement Considerations

The DAC70504RTET serves as a direct functional substitute with identical electrical characteristics. Verify that the alternative suffix matches the required packaging format and ensure thermal performance remains within specified limits during replacement.
