DAC7642VFBR

Digital To Analog Converters Overview

The DAC7642VFBR is a dual-channel, 16-bit digital-to-analog converter manufactured by Texas Instruments. It features a parallel interface and provides buffered voltage outputs. The device operates with analog supply voltages of ±5 V and a digital supply of 5 V. Key performance parameters include a sampling rate of 100 ksps and a settling time of 10 µs. It is housed in a 32-pin LQFP package and supports an operating temperature range from -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Dual-channel architecture providing independent 16-bit resolution for two separate output channels.
• Integrated buffered voltage outputs designed to drive external loads without requiring additional amplification stages.
• Parallel data interface supporting standard microcontroller or DSP connections for high-speed data transfer.

Digital To Analog Converters Applications

• Industrial process control systems requiring precise analog signal generation.
• Programmable power supplies needing stable voltage references.
• Test and measurement equipment utilizing multi-channel signal synthesis.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'VFBT' against the requested 'VFBR' designation, as packaging variations may exist between tape-and-reel formats. Confirm RoHS compliance status through official datasheets. Ensure the supplier provides valid traceability documentation for industrial-grade components.

Digital To Analog Converters Selection Notes

Select this component when dual-channel 16-bit resolution is required with a parallel interface. Compare against the DAC7632 if SPI connectivity is preferred instead of parallel. Verify that the ±5 V analog supply requirement aligns with the system power architecture before finalizing the design.

Digital To Analog Converters Part Context

This part belongs to the DAC7642 family of 16-bit dual voltage output DACs. It shares functional similarities with the DAC7641 (single channel) and DAC7654 (dual channel). The device is part of Texas Instruments' legacy Burr-Brown portfolio, often used in applications transitioning from older discrete solutions to integrated converters.

Digital To Analog Converters Replacement Considerations

The DAC7642VFR is a pin-compatible alternative within the same series. Check datasheet revisions for any changes in electrical characteristics or pin definitions before substitution.
