DAC7614U/1KG4

Digital To Analog Converters Overview

The DAC7614U/1KG4 is a quad, 12-bit voltage output digital-to-analog converter manufactured by Texas Instruments. It features an R-2R resistor ladder architecture and operates with a serial interface compatible with standard SPI protocols. The device supports a sampling rate of 89 kS/s per channel and achieves a settling time of 10 microseconds. It functions within a supply voltage range of 3 V to 3.6 V and operates across a temperature range of -40°C to +85°C. Packaged in a 16-pin SOIC format on a reel, it integrates four independent converters for multi-channel signal generation.

Digital To Analog Converters Feature Summary

Digital To Analog Converters Procurement Notes

Verify the specific suffix '1KG4' against official manufacturer documentation to confirm packaging configuration and RoHS compliance status. Ensure the source document explicitly identifies this part number as distinct from other variants in the DAC7614 family. Cross-reference the datasheet revision history to validate current production status and any potential obsolescence notices prior to procurement planning.

Digital To Analog Converters Selection Notes

Select this component when a design requires four isolated 12-bit voltage outputs with serial control. Verify that the system logic levels are compatible with the specified 3 V to 3.6 V operating range. Confirm that the 10 microsecond settling time meets the application's update rate requirements. Ensure the PCB layout accommodates the 16-pin SOIC footprint and thermal dissipation needs for the specified power consumption.

Digital To Analog Converters Part Context

This component belongs to the DAC7614 series of precision digital-to-analog converters. The series is characterized by its quad-channel configuration and low-power operation suitable for portable applications. The DAC7614U variant specifically denotes the plastic SOIC package option, while the '/1K' indicates reel packaging. The 'G4' suffix typically relates to lead-free manufacturing processes compliant with environmental standards.

Digital To Analog Converters Replacement Considerations

The DAC7614E/1K serves as a functional alternative offering identical electrical specifications but utilizes an SSOP-20 package instead of the SOIC-16 form factor. Designers must account for pinout differences and physical footprint changes when substituting between these package types.
