DAC5672IPFB

Digital To Analog Converters Overview

The DAC5672IPFB is a dual-channel, 14-bit digital-to-analog converter (DAC) manufactured by Texas Instruments. It supports a maximum sampling rate of 275 MS/s with a settling time of 20 ns. The device features current source outputs and accepts parallel digital inputs. It operates on a single 3.3 V analog and digital supply voltage. Key performance metrics include a differential nonlinearity (DNL) of +/- 0.75 LSB, integral nonlinearity (INL) of +/- 1.1 LSB, and an spurious-free dynamic range (SFDR) of 84 dB. The component is housed in a 48-lead TQFP package and functions within a temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Dual-channel architecture providing independent signal processing for two output paths.
• High-speed data conversion capability supporting up to 275 MSPS sampling rates.
• Low power consumption design suitable for battery-operated or thermally constrained systems.
• Integrated offset binary input format compatibility for direct DSP interfacing.

Digital To Analog Converters Procurement Notes

Verify the suffix 'IPFB' against the official datasheet to confirm the specific tape-and-reel packaging configuration. Ensure the order matches the required moisture sensitivity level and lead finish specifications defined by Texas Instruments for this exact part number variant.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution with 14-bit resolution and high linearity is required. Compare DNL and INL specifications against system noise floors. Verify that the parallel interface timing requirements align with the host processor's capabilities and that the 3.3 V supply constraint fits the system power budget.

Digital To Analog Converters Part Context

This device belongs to the DAC5672 family from Texas Instruments, designed for high-performance analog signal generation. It shares architectural similarities with the DAC5662 and DAC5652 but offers higher resolution. The IPFB designation indicates a specific commercial-grade package and reel option within the broader product line.

Digital To Analog Converters Replacement Considerations

The DAC5672A series serves as a functional equivalent with identical electrical characteristics. Check for pin-compatible alternatives such as the DAC5662 if lower resolution is acceptable. Verify that any substitute maintains the same 275 MSPS speed and 14-bit accuracy requirements.

Digital To Analog Converters FAQ
