ADS54J54IRGCR

Analog To Digital Converters (ADC) Overview

The ADS54J54IRGCR is a quad-channel, 14-bit analog-to-digital converter (ADC) from Texas Instruments. It operates at a sampling rate of 500 MSPS and utilizes a pipeline architecture. The device features differential analog inputs with an internal buffer for high impedance. Power requirements include 1.9 V for analog and digital supplies. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 72 dBFS, an Effective Number of Bits (ENOB) of 11.3 bits, and a Spurious-Free Dynamic Range (SFDR) of 86 dBc. The component is housed in a 72-pin VQFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRGCR against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration. Ensure that export control documentation is prepared if required by local regulations, as indicated for this product family. Confirm RoHS compliance status through the official environmental filing before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a system requires four independent channels with 14-bit resolution at 500 MSPS. The integrated DDC functionality reduces downstream FPGA processing load by allowing direct output rates up to 200 MHz. Compare SNR and SFDR specifications against alternative ADCs to ensure compatibility with the target dynamic range requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS54J series of high-performance telecom receiver devices. It shares architectural similarities with the ADS54J64 but offers four channels instead of two. The device is designed to replace older discrete solutions or lower-speed ADCs in modern wireless infrastructure applications requiring high linearity and bandwidth.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the ADS54J64, though channel count differs. Verify electrical parameters such as power consumption and interface speed when substituting with other quad-channel ADCs like the ADS58J63.
