ADC32RF55IRTDT

Analog To Digital Converters (ADC) Overview

The ADC32RF55IRTDT is a dual-channel, 14-bit analog-to-digital converter (ADC) from Texas Instruments. It features a single-core non-interleaved architecture with a sampling rate of 3.0 GSPS and supports RF input frequencies up to 3 GHz. The device provides a noise spectral density of -155.6 dBFS/Hz without averaging, improving to -160.4 dBFS/Hz with 4x averaging. It utilizes a JESD204B serial data interface supporting lane rates up to 13 Gbps with subclass 1 deterministic latency. Each channel includes four digital down-converters (DDCs) with 48-bit numerically controlled oscillators (NCOs). Power consumption is 2.6 W per channel at 3 GSPS with 2x averaging. The component operates on 1.8 V and 1.2 V supplies within an operating temperature range of -40°C to 85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's package option addendum to confirm pin configuration and thermal pad specifications. Ensure that the procurement documentation matches the required RoHS compliance status and production data revision level. Cross-reference the part number with official distributor catalogs to validate authenticity and traceability before finalizing acquisition.

Analog To Digital Converters (ADC) Selection Notes

Select the ADC32RF55IRTDT when a 3.0 GSPS sampling rate is required for direct RF sampling applications. Compare it against the ADC32RF54 if a lower 2.6 GSPS rate suffices for your bandwidth needs. Consider the power dissipation requirements, as the device consumes significant current at maximum sampling speeds. Evaluate the need for internal DDCs and averaging features to determine if this integrated solution meets your system complexity constraints.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC32RF5x family of high-speed RF sampling data converters. It shares architectural similarities with the ADC32RF54 but offers a higher maximum sampling rate of 3.0 GSPS compared to the 2.6 GSPS limit of its counterpart. Both devices utilize the same VQFN package and support identical JESD204B interface standards for high-throughput data transmission in demanding signal processing environments.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC32RF54 serves as a functional substitute within the same family, offering identical features at a reduced 2.6 GSPS sampling rate. Verify compatibility regarding clock frequency limits and power supply configurations when substituting between these two models.
