DAC7621EB/1K

Digital To Analog Converters Overview

The DAC7621EB/1K is a quad, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features parallel input architecture and provides buffered voltage outputs. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports an update rate of 89 kS/s per channel. Key electrical specifications include a settling time of 10 µs and a gain error of 0.2% FSR. It is housed in a 20-pin SSOP package and functions across an industrial temperature range from -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Integrates four independent 12-bit DAC channels with parallel data interfaces for simultaneous multi-channel control.
• Provides buffered voltage outputs capable of driving external loads without additional amplification stages.
• Utilizes R-2R resistor ladder architecture to ensure consistent linearity and precision across the full-scale range.

Digital To Analog Converters Applications

• Industrial process control systems requiring precise analog signal generation.
• Multi-channel data acquisition systems needing synchronized voltage references.
• Programmable power supply designs utilizing multiple output rails.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'EB/1K' against the manufacturer's current datasheet to confirm package type and reel quantity. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the part number with official Texas Instruments documentation to validate availability and lead times before finalizing procurement plans.

Digital To Analog Converters Selection Notes

Select this component when a design requires four independent 12-bit voltage outputs controlled via parallel logic. It is suitable for applications demanding moderate speed (89 kS/s) and low power consumption compared to higher-resolution alternatives. Consider the SSOP-20 footprint during PCB layout to ensure adequate thermal dissipation and pin spacing compatibility.

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, offering a cost-effective solution for multi-output applications. The device complements other serial-input models like the DAC7615 by providing parallel interface options for faster data throughput requirements.

Digital To Analog Converters Replacement Considerations

The DAC7621E is a non-reel equivalent version of the same functional device. For single-channel requirements, the DAC7611 offers similar 12-bit resolution with serial input. Verify pinout compatibility when substituting with other quad-DAC families from different manufacturers.
