DAC7678SRGER

Digital To Analog Converters Overview

The DAC7678SRGER is an octal digital-to-analog converter manufactured by Texas Instruments, featuring 12-bit resolution and eight independent voltage outputs. It operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. The device utilizes a 2-Wire I2C compatible interface for data input and communication. Key performance specifications include a settling time of 12 µs, a sampling rate of 55.55 kS/s, and a typical operating current of 1.49 mA. Integral nonlinearity is specified at ±0.3 LSB, while differential nonlinearity is ±0.1 LSB. The component is housed in a 24-pin VQFN package with a 4x4 mm footprint and supports an extended industrial temperature range from -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Ultra-low glitch energy design minimizes output transients during code transitions.
• Integrated reset function forces all channels to mid-scale upon power-up or system reset.
• Cost-optimized architecture provides high channel density within a compact surface-mount package.

Digital To Analog Converters Applications

• Process control systems requiring multi-channel signal generation
• Programmable gain amplifiers and variable reference sources
• Portable instrumentation with battery-powered constraints

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'GER' against the manufacturer's official documentation to confirm the tape-and-reel packaging configuration and moisture sensitivity level. Ensure compatibility with standard I2C bus protocols and check for any regional compliance requirements such as RoHS status 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 design. It serves as a suitable alternative to buffered variants like the DAC7578 series if external buffering is not necessary. Consider the unbuffered voltage output capability and the specific glitch energy characteristics relative to the application's noise immunity requirements.

Digital To Analog Converters Part Context

This part belongs to the DAC7678 family of octal DACs, which shares architectural similarities with the DAC7578 and DAC5578 series. While the DAC7578 offers buffered outputs and lower power consumption, the DAC7678 focuses on ultra-low glitch performance. The SRGER designation specifically identifies the VQFN-24 package variant supplied in a reel format for automated assembly processes.

Digital To Analog Converters Replacement Considerations

DAC7678SRGET: Identical electrical specifications and functionality; differs only in packaging format (cut tape vs. reel). DAC7578SRGER: Offers buffered outputs and lower power consumption but lacks the ultra-low glitch specification of the DAC7678 series.
