DAC7621E/1K

Digital To Analog Converters Overview

The DAC7621E/1K is a quad, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features parallel input architecture and provides voltage output across four independent channels. The device utilizes an R-2R resistor network structure for conversion. It operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range from -40°C to +85°C. The component is housed in a 20-pin SSOP package designed for surface mount installation.

Digital To Analog Converters Feature Summary

• Quad-channel configuration providing four independent 12-bit DACs
• Parallel data interface for direct microcontroller connection
• Voltage output capability with R-2R architecture

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Portable instrumentation utilizing low-voltage power supplies
• Battery-powered test equipment needing precise analog reference outputs

Digital To Analog Converters Procurement Notes

Verify the specific suffix '1K' indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets. Ensure the SSOP-20 footprint matches the target PCB design constraints before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when four independent 12-bit voltage outputs are required with parallel interfacing. Compare against serial-input alternatives like the DAC7615 if pin count reduction is necessary. Evaluate settling time and gain error specifications against system accuracy requirements to ensure compatibility with application performance standards.

Digital To Analog Converters Part Context

This part belongs to the DAC76xx series of precision digital-to-analog converters from Texas Instruments. It serves as a quad-channel variant within the family, distinct from single-channel models like the DAC7621. The series is characterized by low power consumption and compatibility with standard 5V logic systems.

Digital To Analog Converters Replacement Considerations

The DAC7621E is a tube-packaged equivalent offering identical electrical specifications. Verify package compatibility between SSOP-20 reel and tube formats during substitution planning.
