THS5671AIDW

Digital To Analog Converters Overview

The THS5671AIDW is a 14-bit digital-to-analog converter (DAC) from the CommsDAC family, optimized for wired and wireless communication systems. It features a maximum update rate of 125 MSPS at DVDD voltages between 4.5 V and 5.5 V, reducing to 100 MSPS at lower digital supply levels. The device operates with an analog supply of 4.5 V to 5.5 V and a digital supply of 3 V to 5.5 V. It provides differential scalable current outputs ranging from 2 mA to 20 mA full-scale. Key performance metrics include a Spurious Free Dynamic Range (SFDR) of 63 dBc at 40 MHz output and a settling time of 35 ns. Power dissipation is 175 mW at 5 V, with a sleep mode reducing standby power to approximately 25 mW.

Digital To Analog Converters Feature Summary

• Integrated 1.2 V temperature-compensated bandgap reference with adjustable full-scale output current control via external resistor or external reference input.
• Differential current-steering architecture providing high output impedance (>300 kΩ) and noise cancellation capabilities without requiring external output buffers.
• Flexible digital interface supporting both straight binary and two's complement input formats with CMOS-compatible logic levels.

Digital To Analog Converters Applications

• Digital data transmission in wired communication systems
• Wireless communication base station signal generation
• Direct digital synthesis (DDS) applications

Digital To Analog Converters Procurement Notes

Verify the specific package marking and date code against the manufacturer's latest documentation to ensure authenticity. Confirm that the component meets RoHS compliance requirements if mandated by your system specifications. Check for any pin-compatible alternatives within the same product family if supply constraints exist.

Digital To Analog Converters Selection Notes

Select this component when 14-bit resolution and high-speed operation up to 125 MSPS are required for communication signals. Ensure the design accommodates the 4.5 V to 5.5 V analog supply range. Consider the TSSOP variant if space constraints favor a smaller footprint, as the SOIC package is wider.

Digital To Analog Converters Part Context

The THS5671AIDW belongs to the Texas Instruments CommsDAC series, which includes pin-compatible 8-bit, 10-bit, and 12-bit variants. This specific part number denotes the 14-bit resolution version housed in a 28-pin Small Outline Integrated Circuit (SOIC) package. It shares the same pinout and interface characteristics as other members of the family.

Digital To Analog Converters Replacement Considerations

Pin-compatible substitutes within the same family include the THS5661A (12-bit), THS5651A (10-bit), and THS5641A (8-bit). These devices offer identical interfaces and packages but with reduced resolution and potentially different power profiles.
