DAC70501ZDQFR

Digital To Analog Converters Overview

The DAC70501ZDQFR is a true 14-bit, single-channel digital-to-analog converter manufactured by Texas Instruments. It features an R-2R architecture with a settling time of 5 µs and supports both SPI and I2C interfaces. The device operates on analog and digital supply voltages ranging from 2.7 V to 5.5 V. It provides a buffered voltage output with a maximum differential nonlinearity (DNL) and integral nonlinearity (INL) of ±1 LSB. The gain error is specified at 0.08% FSR. Operating temperatures range from -40°C to +125°C. The component is housed in an 8-pin WSON package.

Digital To Analog Converters Feature Summary

• Integrated internal voltage reference providing precise full-scale output ranges
• Configurable serial interface supporting standard, fast, and fast-plus I2C modes alongside high-speed SPI
• Power-on reset circuit ensuring deterministic output states upon initialization

Digital To Analog Converters Applications

• Data acquisition systems requiring high precision
• Semiconductor test equipment
• Process analysis instrumentation for pH, gas, and concentration measurement
• Analog output modules in industrial control

Digital To Analog Converters Procurement Notes

Verify the specific suffix ZDQFR against official datasheets to confirm the WSON-8 package and reel packaging configuration. Ensure compatibility with required operating temperature ranges and interface protocols before integration. Cross-reference manufacturer part numbers to avoid substitution errors.

Digital To Analog Converters Selection Notes

Select this component when a single-channel, 14-bit resolution is sufficient for the application. Consider the DAC80501ZDQFR if 16-bit performance is required, or the DAC60501ZDQFR for lower cost with 12-bit resolution. Evaluate power consumption requirements as the device draws 1.5 mA during operation.

Digital To Analog Converters Part Context

This part belongs to the DACx0501 family of high-precision, low-power voltage-output DACs. The family includes 12-bit, 14-bit, and 16-bit variants sharing similar pinouts and functional characteristics. The DAC70501 variant specifically targets applications needing 14-bit accuracy with integrated references and flexible digital interfaces.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include DAC80501ZDQFR (16-bit) and DAC60501ZDQFR (12-bit). Verify pinout compatibility and software register adjustments when migrating between different resolution levels within the series.
