DAC7664YBT

Digital To Analog Converters Overview

The DAC7664YBT is a quad-channel, 16-bit voltage-output digital-to-analog converter manufactured by Texas Instruments. It integrates four independent DACs within a single package, utilizing an R-2R resistor ladder architecture to achieve high resolution and accuracy. The device operates with a digital supply voltage of 5V and analog supplies of ±5V. It features a parallel data interface for straightforward system integration. Key performance specifications include a settling time of 15µs and integral nonlinearity (INL) of ±3 LSB maximum. The component is designed for surface-mount installation in the 64-LQFP package.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'YBT' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 64-LQFP format. Check for RoHS compliance status and environmental certifications required for your target market. Confirm availability through authorized distributors as part numbers may have lifecycle changes.

Digital To Analog Converters Selection Notes

Select this component when a design requires four isolated 16-bit analog channels without the complexity of serial interfaces. Consider the 15µs settling time against your system's update rate requirements. Evaluate the ±5V analog supply requirement against your available power rails. Compare pin count and package size constraints against alternative solutions like the DAC7664YCT if space is limited.

Digital To Analog Converters Part Context

The DAC7664 belongs to Texas Instruments' family of precision digital-to-analog converters. It serves as a quad-channel solution within the broader DAC76xx series, offering higher channel density compared to single-channel counterparts. The device complements other TI data converters by providing a cost-effective approach for applications needing multiple synchronized or independent analog outputs from a single digital source.

Digital To Analog Converters Replacement Considerations

The DAC7664YCT is listed as a manufacturer-recommended alternative. Verify that the package dimensions and pinout are identical before substitution. Check for any differences in electrical characteristics or operating temperature ranges between the YBT and YCT suffixes.
