ADS5481IRGCT

Analog To Digital Converters (ADC) Overview

The ADS5481IRGCT is a single-channel, 16-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It supports sampling rates of 80 MSPS, 105 MSPS, and 135 MSPS. The device utilizes a pipeline architecture with differential inputs and provides LVDS digital output interfaces. It operates on a single 3.3V analog supply and a 1.8V digital supply. The component is housed in a 64-pin VQFN package with an exposed pad for thermal management.

Analog To Digital Converters (ADC) Feature Summary

• Supports multiple sampling rate configurations including 80, 105, and 135 MSPS
• Integrates internal voltage reference and clock driver circuits
• Features low-power operation optimized for high-speed data acquisition

Analog To Digital Converters (ADC) Applications

• Software-defined radio systems
• Wireless local loop infrastructure
• Point-to-point microwave communication links

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and lead-free status as per manufacturer standards. Confirm the 'T' suffix denotes tape-and-reel packaging suitable for automated surface-mount assembly. Ensure the IR designation matches the required industrial temperature range specifications for the target application environment.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-resolution 16-bit conversion is required at speeds up to 135 MSPS. Consider the power consumption trade-offs between the different supported sampling rates. Verify that the system can accommodate the LVDS interface requirements and the specific 3.3V/1.8V dual-supply configuration.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS5481 family of high-performance ADCs from Texas Instruments. It serves as a single-channel variant within a series designed for demanding RF and baseband applications. The device complements other multi-channel or lower-resolution options in the broader data converter portfolio.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible alternatives within the same family include ADS5481IRGCR. Cross-vendor replacements such as Analog Devices AD9265 may require significant schematic and layout modifications due to interface and pinout differences.
