DAC3282IRGZR

Digital To Analog Converters Overview

The DAC3282IRGZR is a dual-channel, 16-bit digital-to-analog converter manufactured by Texas Instruments. It supports sampling rates up to 625 MSPS with optional 2x interpolation. The device features an 8-bit LVDS input data bus with on-chip termination and utilizes a current sink architecture. Key performance metrics include a settling time of 10.4 ns, an SFDR of 83 dB, and an SNR of 77 dB. It operates within a supply voltage range of 3V to 3.6V for analog and 1.7V to 1.9V for digital sections. The component is housed in a 48-VQFN package and functions within a temperature range of -40°C to +85°C.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'RGZR' corresponds to the tape-and-reel packaging variant when ordering. Confirm that the design accommodates the required analog and digital supply voltages (3V-3.6V and 1.7V-1.9V respectively). Ensure the PCB layout supports the 48-VQFN footprint and thermal requirements for continuous operation at maximum sampling rates. Check for RoHS compliance status if environmental regulations are critical to the project specifications.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution with 16-bit precision and high bandwidth is required. The integrated interpolation feature reduces the burden on upstream digital processing. Consider the LVDS interface compatibility with existing FPGA or DSP platforms. Evaluate the power consumption against system thermal constraints, as high-speed operation impacts overall energy efficiency. Compare against the DAC3283 if higher sampling speeds are needed.

Digital To Analog Converters Part Context

This part belongs to the DAC328x family of high-performance data converters from Texas Instruments. It shares architectural similarities with the DAC3283 but offers a slightly lower maximum sampling rate of 625 MSPS compared to the 800 MSPS of its sibling. Both devices utilize the same VQFN-48 package and similar interface protocols, facilitating potential design reuse across different bandwidth requirements within the same product line.

Digital To Analog Converters Replacement Considerations

The DAC3283IRGZR serves as a higher-speed alternative within the same package and family. For direct pin-compatible substitution, verify that the increased 800 MSPS capability does not exceed system clock limits. No other direct cross-model replacements are documented in the provided source material.
