ADC3649IRTDT

Analog To Digital Converters (ADC) Overview

The ADC3649IRTDT is a dual-channel, 14-bit analog-to-digital converter with a maximum sampling rate of 500MSPS. It features a single-core non-interleaved architecture and delivers a noise spectral density of -158.5dBFS/Hz at full speed. The device includes an optional quad-band digital down-converter (DDC) supporting decimation ratios from /2 to /32768. Power consumption is rated at 300mW per channel at 500MSPS. It utilizes buffered differential analog inputs with programmable 100Ω or 200Ω termination and offers flexible DDR or serial LVDS digital output interfaces.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package type and temperature rating. Confirm that the required supply voltages and clock frequencies align with the recommended operating conditions specified in the datasheet before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high dynamic range and low noise are critical for dual-channel applications. Compare performance metrics against the ADC3648 if lower sampling rates suffice, as it offers similar resolution but reduced power consumption at 250MSPS. Ensure the system can support the required 1.8V and 1.2V supply rails.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC364x family, which also includes the ADC3648. Both devices share identical resolution and architecture but differ in maximum sampling speed. The ADC3649 provides the higher 500MSPS throughput required for wider bandwidth signal processing tasks compared to its 250MSPS counterpart.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC3648 serves as a lower-speed alternative within the same family. Verify compatibility regarding pinout and software configuration if substituting between these two models.
