DAC7678SRGET

Digital To Analog Converters Overview

The DAC7678SRGET is an octal, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features a serial interface compatible with standard I2C protocols and operates within a supply voltage range of 2.7 V to 5.5 V for both analog and digital domains. The device provides buffered voltage outputs with a settling time of 12 µs and a sampling rate of 55.55 kS/s. Key performance metrics include a differential nonlinearity (DNL) of ±0.1 LSB and integral nonlinearity (INL) of ±0.3 LSB. It functions reliably across an extended temperature range from -40°C to +125°C and is housed in a compact 24-pin VQFN package.

Digital To Analog Converters Feature Summary

• Octal architecture providing eight independent 12-bit channels in a single component
• I2C-compatible serial interface enabling simplified system connectivity
• Integrated reset function that returns outputs to mid-scale upon power-up or reset assertion
• Low glitch impulse characteristic suitable for precision signal generation applications

Digital To Analog Converters Applications

• Process control systems requiring multi-channel analog output
• Battery-powered instrumentation utilizing low supply voltages
• Data acquisition systems needing precise voltage references
• Industrial automation controllers with space-constrained PCB layouts

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'GET' confirms the tape-and-reel packaging format when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required operating temperature range for the intended environment. Cross-reference the datasheet revision to validate electrical characteristics against current production standards.

Digital To Analog Converters Selection Notes

Select this component when multiple isolated voltage outputs are required without external multiplexing. Compare DNL and INL specifications against application tolerance requirements to ensure accuracy. Evaluate the 12 µs settling time against system update speed constraints. Consider the VQFN-24 footprint dimensions during mechanical design and thermal management planning.

Digital To Analog Converters Part Context

This part belongs to the DAC7678 family of octal DACs designed for cost-sensitive, high-channel-count applications. It shares architectural similarities with the DAC7578 but differs in specific linearity and power optimization targets. The SRGET suffix indicates surface-mount packaging optimized for automated assembly processes in high-volume manufacturing environments.

Digital To Analog Converters Replacement Considerations

The DAC7678SRGER serves as a direct pin-compatible alternative with identical electrical specifications. Verify package marking differences and reel configuration requirements when substituting between GET and GER suffixes.
