DAC1627D1G25HN-C1

Digital To Analog Converters Overview

The DAC1627D1G25HN-C1 is a dual-channel, high-speed digital-to-analog converter manufactured by Renesas Electronics Corporation. It integrates two independent 14-bit DACs capable of operating at sampling rates up to 2.5 gigasamples per second (GSps). The device utilizes advanced interpolation filtering technology to support input data rates significantly higher than the Nyquist frequency, reducing the required interface bandwidth. Designed for demanding signal processing applications, it features low power consumption relative to its performance class and includes integrated output amplifiers. The component is housed in a specialized high-pin-count package optimized for thermal dissipation and signal integrity in dense PCB layouts.

Digital To Analog Converters Feature Summary

• Medical imaging equipment such as ultrasound scanners

Digital To Analog Converters Procurement Notes

Verify the manufacturer designation on the component marking against official Renesas documentation to confirm authenticity. Ensure the suffix matches the specified package and temperature grade. Request traceability documents from authorized distributors to mitigate counterfeiting risks associated with high-performance mixed-signal components.

Digital To Analog Converters Selection Notes

Evaluate the input interface compatibility with the host system's data bus speed and protocol. Consider the thermal management requirements due to the high switching activity at 2.5 GSps. Compare power supply noise sensitivity and jitter tolerance against the application's signal-to-noise ratio requirements. Verify that the available clocking infrastructure meets the phase noise specifications necessary for optimal spurious-free dynamic range.

Digital To Analog Converters Part Context

This component belongs to the DSPEED-DAC family of high-speed converters developed by Integrated Device Technology (IDT), which was subsequently acquired by Renesas Electronics. The series is characterized by its use in high-frequency analog signal generation where speed and resolution are critical. The specific model denotes the dual-channel variant with 2.5 GSps capability, distinguishing it from lower-speed or single-channel counterparts within the same product line.

Digital To Analog Converters Replacement Considerations

Potential substitutes include other dual-channel 14-bit DACs from the same family with compatible pinouts, such as the DAC1627D1G0HN-C1 for lower speed requirements. Cross-reference pin assignments and register maps before substitution to ensure functional compatibility without hardware redesign.
