DAC14135MTX

Digital To Analog Converters Overview

The DAC14135MTX is a monolithic 14-bit, 135MSPS digital-to-analog converter optimized for high-resolution and wide dynamic range applications. It features differential current outputs, an integrated bandgap voltage reference, and TTL/CMOS compatible inputs. The device operates from a single +5V analog supply and supports +3.3V or +5V digital supplies. Key performance metrics include an 85dBc SFDR at 1MHz output and a full-scale current of 20mA. Packaged in a compact 48-pin TSSOP, it functions within an industrial temperature range of -40°C to +85°C.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'MTX' corresponds to the tape and reel packaging format containing 1000 pieces per reel. Confirm that the component is sourced from authorized distributors to ensure authenticity and traceability. Check for any recent lifecycle status updates regarding discontinuation or replacement recommendations from Texas Instruments.

Digital To Analog Converters Selection Notes

Select this component when a high sampling rate of up to 135MSPS with 14-bit resolution is required. Ensure the design accommodates differential current outputs terminated into 50-ohm loads. Verify compatibility with +3.3V or +5V digital logic levels and confirm that the power supply constraints align with the specified analog and digital voltage requirements.

Digital To Analog Converters Part Context

The DAC14135 belongs to the high-speed digital-to-analog converter family originally developed by National Semiconductor and acquired by Texas Instruments. It is designed for communication infrastructure where space efficiency and signal integrity are critical. The MTX variant specifically denotes the reel-packaged version suitable for automated surface-mount assembly processes.
