DAC14135MT/NOPB

Digital To Analog Converters Overview

The DAC14135MT/NOPB is a monolithic 14-bit, 135MSPS digital-to-analog converter designed for high-resolution and wide dynamic range applications. It features differential current outputs, an integrated band-gap voltage reference, and TTL/CMOS compatible inputs. The device operates from a single +5V analog supply and a +3.3V or +5V digital supply. Key performance metrics include an 85dBc SFDR at 1MHz output frequency and a full-scale current of 20mA. It is housed in a compact 48-pin TSSOP package and functions within an industrial temperature range of -40°C to +85°C.

Digital To Analog Converters Procurement Notes

Verify the component origin as Texas Instruments, noting its acquisition of National Semiconductor. Confirm that the specific ordering suffix matches the required package type and temperature rating. Ensure the datasheet version aligns with the latest specifications provided by the manufacturer before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this model when a 14-bit resolution and 135MSPS sampling rate are required in a small footprint. Consider the +5V analog supply requirement and the option for +3.3V digital operation. Evaluate the differential output topology against system impedance needs. Verify thermal management requirements for the 48-pin TSSOP package under maximum operating conditions.

Digital To Analog Converters Part Context

This component belongs to the DAC14135 series of high-speed digital-to-analog converters originally developed by National Semiconductor.
