DAC7643VFBT

Digital To Analog Converters Overview

The DAC7643VFBT is a dual-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features a parallel interface and provides voltage outputs with a settling time of 10 microseconds. The device operates on a single 5 V analog supply and a 5 V digital supply. It is housed in a 32-lead LQFP package suitable for surface mount installation. The component supports an operating temperature range from -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Dual-channel architecture providing independent analog output control
• 12-bit resolution for precise signal generation
• Parallel interface compatibility for direct microcontroller connection

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Portable instrumentation utilizing low power consumption
• Battery-powered test equipment needing stable voltage references

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'VFBT' against official Texas Instruments documentation to confirm the tape and reel packaging configuration. Ensure the order matches the exact pinout and electrical specifications defined in the current datasheet revision before procurement.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution with 12-bit resolution is required. Compare against the DAC7642 if higher 16-bit precision is necessary. Verify that the parallel interface meets the system's timing requirements and that the 5 V supply voltage aligns with the design constraints.

Digital To Analog Converters Part Context

This part belongs to the DAC764x family of dual DACs from Texas Instruments. It shares architectural similarities with the DAC7642 but offers 12-bit resolution instead of 16-bit. The family is designed for applications balancing performance with power efficiency in industrial and portable environments.

Digital To Analog Converters Replacement Considerations

The DAC7642VFBT serves as a higher-resolution alternative within the same package. Verify pin compatibility and software register mapping differences before substitution.
