DAC7718SRGZT

Digital To Analog Converters Overview

The DAC7718SRGZT is an octal, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features a resistor-string architecture with buffered voltage outputs and supports SPI-compatible serial interfaces. The device operates on dual power supplies ranging from ±4.5 V to 18 V for analog circuits and 2.7 V to 5.5 V for digital logic. Key performance metrics include a settling time of 15 µs, maximum integral nonlinearity (INL) of ±1 LSB, and differential nonlinearity (DNL) of ±1 LSB. It functions within a temperature range of -40°C to +105°C and is housed in a 48-VQFN package.

Digital To Analog Converters Feature Summary

• Octal configuration providing eight independent 12-bit channels in a single integrated circuit
• Integrated output buffers designed to drive capacitive loads without external components
• Serial interface compatibility supporting standard DSP, Microwire, QSPI, and SPI protocols
• High precision linearity specifications ensuring accurate signal reproduction across the full scale

Digital To Analog Converters Applications

• Multi-channel data acquisition systems requiring simultaneous analog output generation
• Industrial process control loops utilizing multiple isolated or shared reference signals
• Programmable test and measurement equipment generating complex waveform patterns
• Automotive sensor simulation platforms requiring high channel density

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'SRGZT' against the manufacturer's current datasheet to confirm package dimensions and tape-and-reel specifications. Ensure that the ordering documentation explicitly matches the 48-VQFN footprint and thermal pad requirements. Cross-reference the RoHS compliance status with regional environmental regulations prior to final procurement authorization.

Digital To Analog Converters Selection Notes

Select this component when an application demands eight synchronized low-speed analog outputs with moderate precision. The 15 µs settling time suits applications where update rates are below 66 kS/s per channel. Consider alternative devices if higher resolution or faster conversion speeds are required, as this part prioritizes channel count over individual channel bandwidth.

Digital To Analog Converters Part Context

This device belongs to the DAC7718 family of octal DACs. It shares architectural similarities with other Texas Instruments resistor-string converters but is distinct in its 12-bit resolution and specific pinout configuration. The SRGZT designation indicates the surface-mount VQFN variant optimized for automated assembly processes.

Digital To Analog Converters Replacement Considerations

Direct functional replacements may include other octal DACs from the same manufacturer series. Verify pin-to-pin compatibility and register mapping before substituting. Check for updated revisions that might alter electrical characteristics or packaging standards.
