ADC3569IRTDT

Analog To Digital Converters (ADC) Overview

The ADC3569IRTDT is a single-channel, 16-bit analog-to-digital converter manufactured by Texas Instruments. It supports a maximum sampling rate of 500 MSPS and utilizes a non-interleaved architecture to achieve high signal integrity. The device features buffered analog inputs with programmable 100Ω or 200Ω termination and an input full-scale range of 2VPP. Key performance metrics include a noise spectral density of -160.4dBFS/Hz, a typical SNR of 75.6dBFS at 70MHz, and an aperture jitter of 75fs. Power consumption is rated at 435mW at 500MSPS and 369mW at 250MSPS. It integrates four digital down-converters (DDCs) and operates within a temperature range of -40°C to +105°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package and temperature grade alignment. Confirm availability status directly with authorized distributors as supply levels fluctuate. Ensure compliance with RoHS directives and check for any recent product change notifications affecting pinout or electrical specifications prior to finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select the ADC3569IRTDT when a single-channel, high-speed 16-bit conversion is required with integrated digital signal processing. Compare against the dual-channel ADC3669 if multiple channels are needed. Evaluate the power consumption requirements at 500MSPS versus 250MSPS operating rates. Consider the internal reference accuracy versus external reference needs for gain error specifications.

Analog To Digital Converters (ADC) FAQ

What is the maximum decimation ratio supported by the digital down-converters?

The ADC3569 supports decimation ratios ranging from /2 up to /32768.

How does the digital interface adapt based on DDC usage?

In DDC bypass mode, it uses parallel SDR or DDR LVDS. When using decimation, it switches to a serial LVDS interface to reduce lane count.

What is the typical aperture jitter specification?

The typical aperture jitter is 75fs.
