DAC5672AIPFB

Digital To Analog Converters Overview

The DAC5672AIPFB is a dual-channel, 14-bit digital-to-analog converter manufactured by Texas Instruments. It supports a maximum sampling rate of 275 MSPS and features current-output architecture with integrated output amplifiers. The device operates from a single 3.3 V analog supply and accepts parallel digital inputs. Key performance metrics include a spurious-free dynamic range (SFDR) of up to 78 dBc at 100 MHz output frequency and a full-scale current capability of 20 mA per channel. It is housed in a 72-pin LFCSP package designed for high-density surface-mount applications.

Digital To Analog Converters Feature Summary

• Dual-channel architecture providing independent signal processing paths within a single component
• Integrated output amplifiers eliminate the need for external gain stages
• High-speed parallel interface supporting data rates up to 275 MSPS
• Low power consumption design optimized for battery-operated systems

Digital To Analog Converters Applications

• Wireless base station transmitter chains
• Software-defined radio (SDR) platforms
• Medical imaging equipment signal generation
• Test and measurement instrument waveform synthesis

Digital To Analog Converters Procurement Notes

Verify the specific suffix IPFB confirms the 72-pin LFCSP package type and commercial temperature grade. Ensure compatibility with the system's voltage levels for both analog supplies and digital logic interfaces before integration. Cross-reference the latest datasheet revision to confirm pinout consistency with existing board designs.

Digital To Analog Converters Selection Notes

Select this component when dual-channel 14-bit resolution and speeds exceeding 200 MSPS are required. Compare against the standard DAC5672 if lower speed requirements allow for cost reduction. Consider the DAC5672A variant specifically for its enhanced linearity specifications compared to earlier generations. Evaluate thermal dissipation requirements given the 20 mA output current capability.

Digital To Analog Converters Part Context

The DAC5672A belongs to Texas Instruments' high-performance DAC family, serving as an upgraded version of the DAC5672. It shares architectural similarities with the DAC5662 but offers higher resolution. This series is widely used in communications infrastructure where precise signal reconstruction at high frequencies is critical for maintaining spectral purity.

Digital To Analog Converters Replacement Considerations

The DAC5672 serves as a direct functional predecessor. For lower resolution needs, the DAC5662 provides a compatible interface with 12-bit accuracy. Verify that any substitute maintains the same 72-pin LFCSP footprint and electrical characteristics to ensure board-level compatibility.
