DAC70502DRXT

Digital To Analog Converters Overview

The DAC70502DRXT is a dual-channel, true 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 includes an integrated precision internal reference. It supports both SPI and I2C serial interfaces, selectable via the SPI2C pin. The DRXT suffix indicates the component is supplied in a cut tape or reel format within a 10-pin WSON package.

Digital To Analog Converters Feature Summary

• Dual-channel architecture providing independent buffered voltage outputs for simultaneous signal generation.
• High linearity performance ensuring accurate analog representation with minimal distortion across the full scale.
• Flexible digital interface compatibility allowing selection between high-speed SPI and standard I2C protocols.

Digital To Analog Converters Applications

• Oscilloscopes and data acquisition systems requiring precise waveform generation
• Battery testing equipment needing stable voltage setpoints
• Semiconductor test fixtures for gain and offset calibration

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm packaging details and availability status. Ensure that the selected variant matches the required thermal and electrical specifications for the intended operating environment before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution with 14-bit resolution and low glitch energy is required. Consider the integrated reference and flexible interface options if board space and external component count need to be minimized compared to discrete solutions.

Digital To Analog Converters Part Context

This part belongs to the DACx0502 family, which also includes the 16-bit DAC80502 and the 12-bit DAC60502. All members share identical pinouts and functional blocks, differing primarily in resolution and associated noise characteristics. This allows for design flexibility while maintaining consistent footprint requirements across product lines.

Digital To Analog Converters Replacement Considerations

The DAC80502 and DAC60502 are pin-compatible alternatives within the same series. Verify that the resolution difference aligns with system accuracy requirements before substituting.
