DAC7641YB/2K

Digital To Analog Converters Overview

The DAC7641YB/2K is a precision, low-power, serial input digital-to-analog converter manufactured by Texas Instruments. It features a 16-bit resolution and delivers a buffered voltage output. The device operates on a single power supply ranging from 2.7 V to 5.5 V and supports standard SPI-compatible serial interfaces. Designed for surface-mount applications, it utilizes an 8-pin MSOP package. Key electrical characteristics include a maximum settling time of 10 microseconds and a guaranteed monotonicity across the full temperature range.

Digital To Analog Converters Feature Summary

• Integrated buffered voltage output stage eliminates the need for external operational amplifiers.
• Serial interface compatibility with standard SPI, Microwire, and QSPI protocols simplifies system integration.
• Internal reference architecture ensures stable performance without requiring external reference components.

Digital To Analog Converters Applications

• Portable instrumentation systems requiring high accuracy and low power consumption.
• Battery-powered data acquisition modules.
• Process control loops involving single-supply operation.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'YB/2K' against the manufacturer's official documentation to confirm the exact packaging configuration and reel quantity. Ensure the component meets the required industrial or commercial temperature specifications for the intended deployment environment before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a single-channel, 16-bit resolution is required with integrated buffering. Compare the 10 microsecond settling time against system bandwidth requirements. Verify that the 2.7 V to 5.5 V supply range aligns with the available power rails in the target design.

Digital To Analog Converters Part Context

This part belongs to the DAC764x family of serial input DACs from Texas Instruments. The family shares common architectural features such as R-2R resistor ladder structures and similar serial communication protocols, differing primarily in resolution, output type, and package options within the series lineup.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible alternatives within the same family include the DAC7641E and DAC7641EB. Verify that the replacement variant matches the required operating temperature range and package dimensions for the existing PCB footprint.
