ADC3549IRTDT

Analog To Digital Converters (ADC) Overview

The ADC3549IRTDT is a single-channel, 14-bit analog-to-digital converter manufactured by Texas Instruments. It supports a maximum sampling rate of 500MSPS and utilizes a non-interleaved architecture to achieve high signal integrity. The device features a noise spectral density of -158.5dBFS/Hz and an aperture jitter of 75fs. It includes four independent digital down-converters (DDCs) with decimation ratios ranging from 2x to 32768x. Power consumption is 435mW at full speed and scales to 369mW at 250MSPS. The component operates within a temperature range of -40°C to +105°C and is housed in a 64-pin VQFN package.

Analog To Digital Converters (ADC) Feature Summary

• Integrates four independent digital down-converters supporting wideband to narrowband decimation with phase-coherent frequency hopping capabilities.
• Employs a single-core non-interleaved architecture to ensure low noise spectral density and high linearity without interleaving spurs.
• Provides flexible LVDS output interfaces that adapt between parallel SDR/DDR modes for bypass operation and serial modes for decimated data transmission.

Analog To Digital Converters (ADC) Applications

• Software defined radio
• Spectrum analyzer
• Radar systems
• Communications infrastructure

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and tape-and-reel specifications. Ensure supply chain channels are authorized distributors to guarantee component authenticity and traceability. Cross-reference the part number with the latest datasheet revision history to account for any updates in mechanical dimensions or electrical characteristics.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-speed conversion path is required with integrated digital signal processing capabilities. The ADC3549 is appropriate for designs needing up to 500MSPS throughput with on-chip decimation to reduce downstream FPGA interface complexity. Compare power dissipation requirements against thermal management capabilities if operating near the maximum sampling rate.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADC354x family, which also includes the ADC3548 variant. Both share identical resolution, architecture, and peripheral features, differing only in their maximum supported sampling rates. The ADC3549 represents the higher-performance option within this specific series, designed for applications demanding greater bandwidth than the 250MSPS limit of its counterpart.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC3548 serves as a lower-speed alternative within the same family. For dual-channel requirements, consider the ADC3649 or ADC3669 series. Verify pin compatibility and software register maps before substituting with other Texas Instruments high-speed ADCs.
