DAC2900Y/250

Digital To Analog Converters Overview

The DAC2900Y/250 is a dual-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It operates at a sample rate of 65 MSPS and utilizes a current-source architecture. The device features parallel CMOS outputs and supports interpolation factors of 1x, 2x, or 4x. It requires an analog supply voltage ranging from 4.75 V to 5.25 V and a digital supply between 3 V and 5 V. Key performance metrics include a typical power dissipation of 310 mW, a spurious-free dynamic range (SFDR) of 80 dB, and a differential nonlinearity (DNL) of +/- 1 LSB. It is housed in a 48-lead HTQFP package and functions within a temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Dual-channel architecture with integrated 4x interpolation capability for enhanced spectral purity.
• Low-power design optimized for battery-operated applications with typical consumption of 310 mW.
• High-speed parallel interface supporting data rates up to 65 MSPS.

Digital To Analog Converters Procurement Notes

Verify the specific suffix against official documentation to confirm packaging and environmental compliance. Confirm that the ordering code matches the required tape-and-reel quantity. Ensure compatibility with existing board layouts regarding the HTQFP-48 footprint before procurement.

Digital To Analog Converters Selection Notes

Select this component when dual-channel conversion at 65 MSPS is required with low power constraints. Compare against the DAC2902 if higher speeds are needed. Verify that the 12-bit resolution and 80 dB SFDR meet system signal integrity requirements.

Digital To Analog Converters Part Context

This part belongs to the DAC2900 family of high-speed digital-to-analog converters. It shares architectural similarities with the DAC2902 but offers lower speed capabilities. The Y/250 designation indicates the industrial temperature range and reel packaging configuration.

Digital To Analog Converters Replacement Considerations

Publicly confirmed substitute part numbers include DAC2902Y/250, DAC2902Y-250, and DAC2902Y-1K. These alternatives offer similar specifications with potentially different speed grades or packaging options.
