DAC7718SPAG

Digital To Analog Converters Overview

The DAC7718SPAG is an octal, low-power, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features a resistor-string architecture with buffered voltage outputs and supports serial interfaces including SPI, Microwire, and QSPI. The device operates on analog supply voltages ranging from ±4.5V to 18V and digital supplies from 2.7V to 5.5V. Key electrical specifications include a settling time of 15µs, integral nonlinearity (INL) and differential nonlinearity (DNL) of ±1 LSB maximum, and a power consumption of 115 mW. It is housed in a 64-TQFP package and functions within a temperature range of -40°C to +105°C.

Digital To Analog Converters Feature Summary

Digital To Analog Converters Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm pinout compatibility and functional equivalence. Ensure that any ordering variations do not alter the electrical characteristics or package dimensions required for your design. Cross-reference the component marking with the datasheet to authenticate the source and prevent counterfeit risks during procurement.

Digital To Analog Converters Selection Notes

Select this component when an octal configuration with 12-bit resolution and serial interface is required. Consider the ±1 LSB linearity and 15µs settling time for applications demanding moderate precision. Evaluate the power budget against the 115 mW consumption and ensure the operating temperature range aligns with environmental conditions.

Digital To Analog Converters Part Context

This part belongs to the DAC7718 family of octal digital-to-analog converters. It shares architectural similarities with other members like the DAC8218 but differs in resolution and interface specifics. The SPAG suffix indicates a specific package type and temperature rating within the broader product line.

Digital To Analog Converters Replacement Considerations

The DAC7718SPAGR is a tape-and-reel variant of the same device. Verify if reel packaging meets production needs without altering electrical performance.
