DAC2900Y/1K

Digital To Analog Converters Overview

The DAC2900Y/1K is a monolithic, dual-channel, 10-bit Digital-to-Analog Converter (DAC) from Texas Instruments. It operates at a high update rate of 125 MSPS and supports single-supply operation with +3.3V or +5V power rails. The device features an internal reference and delivers high dynamic performance, including a Spurious-Free Dynamic Range (SFDR) of 68 dB at a 20 MHz output frequency. It consumes low power, typically 310 mW at +5V, and exhibits low glitch energy of 2 pV-s. Packaged in a 48-pin TQFP (PFB) suitable for industrial temperatures ranging from -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Dual-channel architecture providing two independent 10-bit digital-to-analog conversion paths within a single monolithic device.
• High-speed data conversion capability optimized for applications requiring a 125 MSPS update rate.
• Integrated internal voltage reference eliminates the need for external reference components, simplifying board design.
• Low glitch energy specification ensures signal integrity during code transitions.

Digital To Analog Converters Applications

• Industrial process control systems requiring precise analog signal generation
• Test and measurement equipment needing high-speed waveform synthesis
• Communication infrastructure utilizing direct digital synthesis techniques

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature range. Confirm that the +3.3V or +5V supply requirements align with the target system design. Ensure the 48-TQFP footprint corresponds to the PCB layout specifications. Check for any specific handling instructions related to electrostatic discharge sensitivity during assembly.

Digital To Analog Converters Selection Notes

Choose this component when dual-channel 10-bit resolution at 125 MSPS is required. Consider the internal reference feature if minimizing external component count is a priority. Evaluate the power consumption against thermal constraints in the application environment. Compare the SFDR performance with system noise floor requirements to ensure adequate signal purity.

Digital To Analog Converters Part Context

The DAC2900 series represents Texas Instruments' high-performance digital-to-analog converter lineup designed for demanding applications. This specific variant offers dual channels, distinguishing it from single-channel counterparts. The Y/1K designation indicates the tape-and-reel packaging format intended for automated surface-mount assembly processes.

Digital To Analog Converters Replacement Considerations

The DAC2902 serves as a functional substitute offering 12-bit resolution at the same speed. Verify pin compatibility and software register settings when migrating between these variants. Ensure the increased resolution meets the specific accuracy requirements of the target application.
