DAC70504RTET

Digital To Analog Converters Overview

The DAC70504RTET 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 consumes 2.8 mA operating current and 17 mW power, functioning within a temperature range of -40°C to +125°C in a WQFN-16 package.

Digital To Analog Converters Feature Summary

• Four independent channels with buffered voltage outputs for simultaneous signal generation
• Integrated reset function allowing return to mid-scale output levels
• Compact WQFN-16 footprint designed for space-constrained surface-mount applications

Digital To Analog Converters Applications

• Portable instrumentation systems requiring multi-channel signal processing
• Battery-powered test equipment utilizing low-power DAC architectures
• Industrial control modules needing high-resolution analog output generation

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'RTET' to confirm the WQFN-16 package type and reel packaging configuration. Ensure compatibility with the required SPI bus speeds and verify that the 1.7 V to 5.5 V digital supply range aligns with the system logic levels. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when four independent 14-bit channels are required within a single compact package. The DAC70504RTET is suitable for designs prioritizing low power consumption alongside moderate speed requirements. Consider the R-2R architecture benefits if internal reference stability is managed externally or if specific linearity characteristics match the application needs better than sigma-delta alternatives.

Digital To Analog Converters Part Context

This part belongs to the DAC70504 series, which provides four-channel solutions in small form factors. It complements other devices like the DAC80504RTET, which offers higher 16-bit resolution but similar interface and package constraints. The series targets applications demanding multiple synchronized analog outputs without occupying excessive board area.

Digital To Analog Converters Replacement Considerations

The DAC70504RTER serves as a tape-and-reel alternative within the same product family. Verify pinout and electrical specifications remain identical before substitution. No cross-manufacturer replacements are documented in the provided source material.
