DAC7642VFT

Digital To Analog Converters Overview

The DAC7642VFT 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 5 V, and a digital supply voltage of 5 V. Key performance specifications include a sampling rate of 100 ks/s and a settling time of 10 µs. It is housed in an LQFP-32 surface-mount 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 directly without additional amplification stages.
• Parallel data interface enabling high-speed data transfer compatible with standard microprocessor systems.

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 'VFT' against the manufacturer's current datasheet to confirm package type and tape-and-reel configuration. Ensure compatibility with 5 V logic levels for the parallel interface. Check RoHS compliance status as indicated in the official documentation before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when dual-channel 16-bit resolution is required with a parallel interface. Consider the 10 µs settling time and 100 ks/s update rate for system timing constraints. Verify that the LQFP-32 package fits the PCB layout requirements and that the 5 V supply rails match the system design.

Digital To Analog Converters Part Context

The DAC7642 belongs to the DAC7642 family of dual 16-bit voltage-output DACs. This series is designed for applications requiring multiple synchronized or independent analog outputs. The VFT suffix specifically denotes the LQFP-32 package variant with reel packaging, distinguishing it from other pin-compatible options like the VFBT.

Digital To Analog Converters Replacement Considerations

Check for direct pin-compatible alternatives within the DAC764x family, such as the DAC7642VFBT, ensuring identical electrical characteristics. Verify if single-channel variants like the DAC7642 require additional circuitry to meet dual-channel requirements.
