DAC70502DRXR

Digital To Analog Converters Overview

The DAC70502DRXR is a dual-channel, 14-bit digital-to-analog converter (DAC) from Texas Instruments. It features buffered voltage outputs with integral nonlinearity (INL) and differential nonlinearity (DNL) of ±1 LSB maximum. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V and supports both SPI and I2C serial interfaces. It includes an internal precision reference and offers power-on-reset functionality to zero scale or midscale. The output settling time is typically 5 µs, and the package is a 10-pin WSON.

Digital To Analog Converters Feature Summary

• Configurable serial interface supporting SPI and I2C protocols
• Integrated precision voltage reference with low drift
• Power-on-reset circuit for controlled startup states

Digital To Analog Converters Applications

• Oscilloscopes and data acquisition systems
• Battery testing and semiconductor test equipment
• LCD test and process analytics instruments
• Analog output modules and DC power supplies

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix DRXR corresponds to the WSON-10 package and reel packaging configuration. Confirm that the internal reference specifications meet the application requirements for temperature stability and noise performance. Ensure compatibility with the system's digital logic levels for the selected serial interface mode.

Digital To Analog Converters Selection Notes

Select this component when dual-channel 14-bit resolution with high accuracy is required in a compact footprint. Consider the internal reference if external components must be minimized. Evaluate the serial interface speed requirements against the supported SPI clock rates or I2C modes. Verify thermal management needs based on the junction-to-ambient resistance values provided in the datasheet.

Digital To Analog Converters Part Context

The DAC70502 belongs to the DACx0502 family, which also includes the 16-bit DAC80502 and the 12-bit DAC60502. These devices share similar pinouts and functional blocks but differ in resolution and reference characteristics. The DRXR suffix indicates the tape and reel packaging format for surface-mount assembly.

Digital To Analog Converters Replacement Considerations

The DAC80502 and DAC60502 are pin-compatible alternatives within the same family offering different resolutions. External verification of electrical parameters is required when substituting these parts to ensure compliance with specific linearity and reference accuracy requirements.
