DAC7664YT

Digital To Analog Converters Overview

The DAC7664YT is a quad, 16-bit voltage output digital-to-analog converter manufactured by Texas Instruments. It features an R-2R architecture with four independent channels operating at a sampling rate of 100 kS/s. The device utilizes a serial interface and provides buffered voltage outputs with a settling time of 15 µs. It operates within a temperature range of -40°C to +85°C and is housed in a 64-LQFP package. Key electrical specifications include a gain error of 0.8% FSR and a typical power consumption of 18 mW.

Digital To Analog Converters Feature Summary

• Integrates four independent 16-bit DAC channels for multi-axis control applications
• Features a serial input interface to minimize pin count and simplify system connectivity
• Includes internal reset functionality to initialize outputs to mid-scale upon power-up

Digital To Analog Converters Applications

• Industrial process control systems requiring precise multi-channel signal generation
• Programmable logic controller (PLC) analog output modules
• Test and measurement equipment needing stable reference voltages

Digital To Analog Converters Procurement Notes

Verify component authenticity through authorized distribution channels due to the prevalence of counterfeits in the market. Confirm that the specific suffix matches the required package and temperature grade. Check for RoHS compliance status as manufacturing processes may evolve. Ensure storage conditions adhere to moisture sensitivity level requirements before reflow soldering.

Digital To Analog Converters Selection Notes

Select this component when high resolution and multiple output channels are required in a compact surface-mount package. Compare against parallel interface alternatives if higher data throughput is necessary. Evaluate the 15 µs settling time against application speed requirements. Consider the serial interface overhead when designing the host microcontroller communication protocol.

Digital To Analog Converters Part Context

This part belongs to the DAC7664 family of precision digital-to-analog converters. It shares architectural similarities with other members like the DAC7664Y but differs in packaging and suffix designations. The series is designed for general-purpose analog output applications where accuracy and channel count are prioritized over ultra-high speed performance.

Digital To Analog Converters Replacement Considerations

Direct substitutes include the DAC7664Y and DAC7664YCTG4 from Texas Instruments. Verify pin compatibility and electrical parameter equivalence before substitution. Alternative families may require schematic modifications due to interface or package differences.
