DAC5675AHFG/EM

Digital To Analog Converters Overview

The DAC5675AHFG/EM is a 14-bit, 400-MSPS digital-to-analog converter manufactured by Texas Instruments. It features a segmented non-transistor current source array architecture with differential scalable current outputs ranging from 2 mA to 20 mA. The device operates on a single 3.3-V supply and utilizes low-voltage differential signaling (LVDS) compatible input interfaces for high-speed data transfer. Key performance metrics include an spurious-free dynamic range (SFDR) of -69 dBc at 70-MHz IF with a 400-MSPS update rate. Power consumption is specified at 820 mW under typical operating conditions of 400 MSPS clock and 70 MHz output frequency.

Digital To Analog Converters Feature Summary

• High-speed data conversion capability supporting up to 400 MSPS update rates for rapid signal processing.
• Low-power LVDS interface design that minimizes electromagnetic interference while maintaining constant power consumption.
• Adjustable differential output current allowing flexible configuration between 2 mA and 20 mA based on application requirements.

Digital To Analog Converters Applications

• Wireless communication systems including CDMA and TDMA cellular base station transceivers
• Cable modem front-end signal generation
• Direct digital synthesis (DDS) for precise frequency generation
• Test and measurement equipment requiring arbitrary waveform generation

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'HFG/EM' against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the HTQFP PowerPad package. Confirm that the manufacturing revision matches the required thermal resistance characteristics for your heat dissipation design.

Digital To Analog Converters Selection Notes

Select this component when a 14-bit resolution and 400-MSPS speed are required for multi-carrier transmission applications. Consider the adjustable output current range if system impedance matching varies. Evaluate the single 3.3-V supply requirement against available power rails. Verify that the LVDS input interface aligns with the driving FPGA or processor capabilities.

Digital To Analog Converters Part Context

The DAC5675 series includes variants such as the DAC5675A and DAC5675-EP. The standard DAC5675 provides general-purpose high-speed conversion, while the -EP variant offers enhanced performance specifications. The DAC5675A typically features updated electrical characteristics compared to the original release. All variants share the same core architecture and pinout compatibility within the family.

Digital To Analog Converters Replacement Considerations

Publicly confirmed substitute part numbers for the DAC5675AHFG/EM were not identified in verified sources. Designers should consult Texas Instruments for direct replacements or evaluate the DAC5675A for potential functional equivalence depending on specific electrical parameter tolerances.
