DAC3174IRGCT

Digital To Analog Converters Overview

The DAC3174IRGCT is a dual-channel, high-speed digital-to-analog converter manufactured by Texas Instruments. It features 14-bit resolution and supports sampling rates up to 500 MSPS. The device utilizes a parallel interface and delivers current outputs with a settling time of 11 ns. It operates on analog supply voltages of 1.8 V or 3.3 V and a digital supply voltage of 1.8 V. Key performance metrics include an SFDR of 82 dB, DNL of 1 LSB, and INL of 2 LSB. Power consumption is rated at 442 mW. The component is housed in a VQFN-64 package and functions within a temperature range of -40°C to +85°C.

Digital To Analog Converters Procurement Notes

Verify the specific suffix IRGCT to confirm the VQFN-64 package type and industrial temperature grade (-40°C to +85°C). Ensure compatibility with the required 1.8 V digital and 1.8/3.3 V analog supply rails during sourcing. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when dual-channel 14-bit performance at 500 MSPS is required. Compare against single-channel variants like the DAC3171 if only one channel is needed. Consider the DAC3174's parallel interface requirements versus serial options if pin count is constrained. Verify that the 11 ns settling time meets system bandwidth specifications.

Digital To Analog Converters Part Context

This part belongs to the DAC317x family of high-speed DACs from Texas Instruments. It shares architectural similarities with the DAC3171 (single-channel) but provides two channels in the same VQFN-64 footprint. The series is designed for demanding RF and communication applications requiring high linearity and speed.

Digital To Analog Converters Replacement Considerations

The DAC3171IRGCT serves as a single-channel alternative within the same package and performance class. For dual-channel needs, verify if legacy parts like the DAC5672 meet lower speed requirements. No direct drop-in replacements are confirmed in public datasheets without functional re-evaluation.
