ADC3669IRTDT

Analog To Digital Converters (ADC) Overview

The ADC3669IRTDT is a dual-channel, 16-bit analog-to-digital converter (ADC) from Texas Instruments operating at a maximum sampling rate of 500 MSPS. It features a single core architecture with a noise spectral density of -160.4 dBFS/Hz and an aperture jitter of 75 fs. The device includes four independent digital down-converters (DDCs) supporting decimation ratios from /2 to /32768. Power consumption is 300 mW per channel at 500 MSPS. It utilizes DDR or serial LVDS interfaces and operates within a temperature range of -40°C to +105°C in a 64-pin VQFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the complete part number including the IRTDT suffix against the official Texas Instruments datasheet to ensure correct package type and temperature rating. Confirm that the specific revision level matches your design requirements. Check for any recent documentation updates regarding pin configurations or electrical characteristics before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high-speed 16-bit conversion at 500 MSPS is required alongside on-chip digital down-conversion capabilities. Ensure the system design accommodates the specified 1.8V and 1.2V supply rails. Verify that the host processor supports either the parallel DDR LVDS or serial LVDS interface protocols defined in the specifications.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADC366x family, which also includes the ADC3668 operating at 250 MSPS. Both share similar architectural features but differ in maximum sampling speed. The ADC3669 represents the higher-performance variant within this dual-channel 16-bit series designed for demanding wideband applications.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC3668 serves as a lower-speed alternative within the same family. For single-channel requirements, consider the ADC3569. Cross-compatibility checks are necessary due to potential differences in power consumption and interface timing between these variants.
