THS5641AIDW

Digital To Analog Converters Overview

The THS5641AIDW is an 8-bit, 100 MSPS digital-to-analog converter (DAC) from the CommsDAC family. It features a current-source-array architecture with differential scalable outputs ranging from 2 mA to 20 mA. The device operates on single supplies of 3 V to 5.5 V for both analog and digital domains. Key performance metrics include a settling time of 35 ns to 0.1%, glitch energy of 5 pV-s, and SINAD of 50 dB at 5 MHz output frequency. It integrates a 1.2 V reference and supports straight binary or two's complement input formats.

Digital To Analog Converters Feature Summary

• Segmented current-steering architecture provides high update rates with low power consumption.
• Differential current outputs enable noise cancellation and increased signal output power.
• On-chip edge-triggered latches simplify interfacing with external logic families.
• Adjustable full-scale current reduces power dissipation without significant performance degradation.

Digital To Analog Converters Applications

• Video applications
• Digital data transmission in wired communication systems
• Digital data transmission in wireless communication systems

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'DW' corresponds to the 28-pin SOIC package and industrial temperature range (-40°C to 85°C). Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure supply voltages remain within the specified 3 V to 5.5 V limits for both analog and digital rails.

Digital To Analog Converters Selection Notes

Select this component when an 8-bit resolution and 100 MSPS update rate are required for communication or video signals. Consider the THS5641AIDW for designs needing low glitch energy and adjustable output current. Verify that the parallel interface timing meets system setup and hold requirements. Evaluate power constraints against the 100 mW typical dissipation at full scale.

Digital To Analog Converters Part Context

The THS5641AIDW belongs to the Texas Instruments CommsDAC product family. This series includes pin-compatible devices with resolutions of 14, 12, 10, and 8 bits. All members share identical interface options and package pinouts, facilitating design scalability across different resolution requirements while maintaining consistent board layout characteristics.

Digital To Analog Converters Replacement Considerations

Pin-compatible alternatives within the same family include THS5641AI (same function, different package variant if applicable), THS5651A (10-bit), THS5661A (12-bit), and THS5671A (14-bit). These devices maintain identical pinouts and interface timing but offer higher resolution. Verify thermal and power specifications when substituting with higher-resolution variants.
