DAC70501MDQFR

Digital To Analog Converters Overview

The DAC70501MDQFR is a true 14-bit, single-channel digital-to-analog converter manufactured by Texas Instruments. It features a buffered voltage output and supports both SPI and I2C serial interfaces. The device operates on analog and digital supply voltages ranging from 2.7 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 ±1 LSB, and a gain error of 0.04%/FSR. It offers a spurious-free dynamic range (SFDR) of 70 dB. The component is housed in a 10-VSSOP package and functions within an industrial temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Integrates a precision internal voltage reference with low temperature drift for stable operation without external components.
• Features a flexible digital interface configurable for either high-speed SPI or standard I2C communication protocols.
• Includes an integrated power-on reset circuit to ensure the DAC output initializes to a defined zero or mid-scale level.

Digital To Analog Converters Applications

• Data acquisition systems requiring high-resolution signal generation
• Semiconductor test equipment and automated testing setups
• Industrial process analysis instruments for pH, gas, and concentration monitoring

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'QF' indicates the tape-and-reel packaging format when ordering. Confirm that the operating environment remains within the specified -40°C to +125°C range. Ensure supply voltages do not exceed the 5.5 V maximum limit. Check for moisture sensitivity levels if the component has been exposed to ambient conditions prior to soldering. Validate pin compatibility with the target PCB footprint.

Digital To Analog Converters Selection Notes

Select this model for applications demanding 14-bit resolution with low power consumption. Consider the internal reference capability if board space for external references is limited. Compare settling times against system update rate requirements. Verify that the chosen serial interface mode aligns with the host controller's available pins. Evaluate the VSSOP package size constraints relative to the assembly process.
