DAC7664YCR

Digital To Analog Converters Overview

The DAC7664YCR is a quad, 16-bit digital-to-analog converter manufactured by Texas Instruments. It features an internal reference and R-2R architecture to provide buffered voltage outputs. The device operates with a single 5V digital supply and dual analog supplies ranging from ±5V to ±15V. Key electrical parameters include a settling time of 15µs, maximum integral nonlinearity (INL) of ±3 LSB, and differential nonlinearity (DNL) of -1/+2 LSB. It utilizes a parallel data interface and functions within a temperature range of -40°C to +85°C in a 64-LQFP package.

Digital To Analog Converters Feature Summary

• Integrates four independent 16-bit voltage output channels on a single chip
• Provides buffered analog outputs for direct driving capability
• Supports standard parallel data interfaces for microcontroller integration
• Includes an internal reference source to simplify circuit design

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Programmable power supply architectures
• Data acquisition systems with multiple analog output requirements

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'YCR' against official Texas Instruments documentation to confirm package type and tape-and-reel status. Ensure compatibility with existing board layouts regarding the 64-LQFP footprint. Check for end-of-life status or recommended new replacements if current stock is limited.

Digital To Analog Converters Selection Notes

Select this component when four synchronized 16-bit voltage outputs are required without external buffering. Compare settling times and linearity specifications against application needs. Consider the parallel interface complexity versus serial alternatives like the DAC7734 if pin count is constrained.

Digital To Analog Converters Part Context

This part belongs to the DAC7664 family of precision digital-to-analog converters. It shares architectural similarities with the DAC7644 but differs in package options and specific manufacturing revisions. The YCR designation typically indicates a specific tape-and-reel packaging variant for automated assembly.

Digital To Analog Converters Replacement Considerations

The DAC7664YCT is listed as a manufacturer-recommended alternative. Verify pinout and electrical equivalence before substitution.
