DAC7678SPW

Digital To Analog Converters Overview

The DAC7678SPW is an octal, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features a low glitch energy design and operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. The device communicates via a 2-Wire I2C-compatible interface and delivers buffered voltage outputs. Key performance metrics include a settling time of 12 µs, a sampling rate of 55.55 kS/s, and a typical operating current of 1.32 mA. Nonlinearity specifications are defined by a differential nonlinearity (DNL) of ±0.1 LSB and an integral nonlinearity (INL) of ±0.3 LSB. It is housed in a 16-pin TSSOP package and supports an extended industrial temperature range from -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Octal architecture providing eight independent 12-bit channels within a compact footprint
• Ultra-low glitch energy design suitable for precision signal generation applications
• Integrated reset function allowing outputs to initialize to mid-scale upon power-up

Digital To Analog Converters Applications

• Multi-channel data acquisition systems requiring synchronized analog output
• Industrial process control loops with multiple sensor simulation points
• Programmable test and measurement equipment generating reference voltages

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'SPW' corresponds to the tube packaging format when sourcing components. Confirm that the order includes the correct moisture sensitivity level handling requirements. Ensure compatibility with standard I2C bus protocols used in the target system design before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when eight simultaneous 12-bit voltage outputs are required in a space-constrained environment. Compare against the DAC7678SRGET variant if reel or cut-tape packaging is preferred over tubes. Consider the DAC7578 series if buffered outputs are strictly necessary rather than unbuffered voltage outputs.

Digital To Analog Converters Part Context

This part belongs to the DAC7678 family of octal DACs from Texas Instruments. It shares core electrical characteristics with variants like the DAC7678SPWR and DAC7678SRGER, differing primarily in packaging type and shipping configuration. The SPW designation specifically identifies the surface-mount TSSOP-16 package form factor.

Digital To Analog Converters Replacement Considerations

The DAC7678SRGET serves as a functional equivalent offering identical electrical performance in a different VQFN-24 package. Designers must account for pinout and thermal pad differences when substituting between TSSOP and QFN packages.
