DAC2900Y/250G4

Digital To Analog Converters Overview

The DAC2900Y/250G4 is a dual-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It operates with a maximum update rate of 250 MSPS and supports parallel CMOS interfaces. The device utilizes a current source architecture and includes internal interpolation capabilities. It functions within an analog supply voltage range of 4.75 V to 5.25 V and a digital supply voltage range of 2.375 V to 2.625 V. The component is housed in a 48-pin TQFP package and is rated for operation across a temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Dual-channel output configuration providing independent signal processing paths
• High-speed data conversion capability supporting up to 250 MSPS update rates
• Integrated interpolation logic to simplify host processor interface requirements

Digital To Analog Converters Applications

• Wireless base station transmitter chains
• Software-defined radio systems
• Test and measurement equipment

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS adherence according to Texas Instruments documentation. Confirm the '250' designation matches the required 250 MSPS speed grade, as other variants exist within the family. Ensure the TQFP-48 package type aligns with your PCB footprint design rules before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when dual-channel performance at 250 MSPS is required with a 12-bit resolution. Compare against the DAC2902 if a lower 125 MSPS rate suffices, or the DAC2904 for quad-channel needs. Verify that the parallel interface and power supply requirements match the system design constraints.

Digital To Analog Converters Part Context

This part belongs to the DAC29xx series of high-speed digital-to-analog converters from Texas Instruments. The series is designed for demanding communication applications requiring precise waveform generation. The DAC2900 specifically addresses dual-channel needs, distinguishing it from single-channel or quad-channel counterparts in the same product line.

Digital To Analog Converters Replacement Considerations

The DAC2900Y/250G4 is functionally equivalent to the DAC2900Y-250G4. Other compatible parts include the DAC2900Y/250 and DAC2900Y-250. Verify pin compatibility and electrical specifications before substituting.
