DAC7664YBR

Digital To Analog Converters Overview

The DAC7664YBR is a quad 16-bit voltage-output digital-to-analog converter manufactured by Texas Instruments. It features an R-2R architecture with internal reference options and operates on a single +5V digital supply and dual ±5V analog supplies. The device provides four independent buffered voltage outputs, each capable of driving loads directly. Key electrical specifications include a settling time of 12 microseconds for full-scale transitions and a serial interface compatible with standard SPI and QSPI protocols. The component is housed in a 28-pin SOIC package and supports an operating temperature range from -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Four independent 16-bit channels with buffered voltage outputs
• Serial interface compatibility with standard communication protocols
• Internal reference voltage generation capability
• Single-supply digital operation with dual analog supply requirements

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Programmable power supply output stages
• Data acquisition system calibration references
• Medical instrumentation signal conditioning

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'YBR' against the manufacturer's current datasheet to confirm package type and tape-and-reel configuration. Ensure that the ordering information matches the required temperature grade and RoHS compliance status for the intended production environment. Cross-reference the part number with official distributor catalogs to confirm availability and authenticity before procurement.

Digital To Analog Converters Selection Notes

Select this component when multiple isolated 16-bit voltage outputs are required within a single integrated circuit. Consider the 12-microsecond settling time for bandwidth limitations in high-speed applications. Verify that the system design accommodates the necessary dual analog supply rails alongside the single digital supply. Evaluate pin compatibility if replacing older variants within the same family.

Digital To Analog Converters Part Context

The DAC7664 belongs to Texas Instruments' broader family of 16-bit digital-to-analog converters. It shares architectural similarities with parts like the DAC7634 and DAC7644 but offers distinct interface and performance characteristics. The YBR designation specifically identifies the 28-pin SOIC package variant with industrial temperature rating, differentiating it from other packaging options available in the product line.

Digital To Analog Converters Replacement Considerations

Direct substitutes include DAC7634YBR and DAC7644YBR from Texas Instruments. These alternatives share similar pinouts and functionality but may differ in specific electrical parameters or interface timing requirements. Verify register compatibility and output drive capabilities before implementing any cross-model replacement.
