ADC32RF54IRTD

Analog To Digital Converters (ADC) Overview

The ADC32RF54IRTD 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 2.6 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 -160.9 dBFS/Hz with 4x averaging. It includes four digital down-converters per channel with 48-bit NCOs for phase-coherent frequency hopping in under 1 µs. Data transmission utilizes the JESD204B interface at lane rates up to 13 Gbps with subclass 1 deterministic latency. Power consumption reaches 5.5 W per channel at 2.6 GSPS with 4x averaging. The component is housed in a 64-pin VQFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type, temperature range, and reel specifications. Ensure compatibility with required power supply voltages and clock inputs before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a fixed 2.6 GSPS sampling rate meets system requirements. Compare performance metrics such as noise spectral density and power dissipation against the ADC32RF55 if higher sampling speeds are necessary. Evaluate thermal management capabilities based on the specified junction-to-ambient resistance values.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC32RF5x family of high-performance RF sampling converters. It shares architectural similarities with the ADC32RF55 but operates at a lower maximum sampling rate of 2.6 GSPS compared to the 3.0 GSPS limit of its counterpart. Both devices utilize the same 64-pin VQFN footprint and support identical digital processing features.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC32RF55 serves as a direct functional alternative within the same family, offering an increased sampling rate of 3.0 GSPS while maintaining the same pinout and feature set. Verify that the application can accommodate the potentially higher power consumption associated with the faster sampling speed.
