ADS5481IRGC25

Analog To Digital Converters (ADC) Overview

The ADS5481IRGC25 is a 16-bit, high-speed analog-to-digital converter (ADC) manufactured by Texas Instruments. It supports sampling rates of up to 135 MSPS and features a pseudo-differential input architecture with an internal reference voltage. The device operates on a single 1.8 V supply and utilizes a low-power CMOS process. Key electrical specifications include a typical noise floor of -140 dBm/Hz and a dynamic range exceeding 78 dB. It employs a standard SPI-compatible digital interface for configuration and data output.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '25' against the official datasheet to confirm it denotes the tape and reel packaging variant rather than a distinct functional revision. Ensure compatibility with existing PCB footprints and verify RoHS compliance status for the specific manufacturing batch before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution at speeds up to 135 MSPS is required within a compact form factor. Consider the internal reference feature if board space is limited. Evaluate the power budget carefully as performance scales with sampling rate, and ensure the system clock jitter requirements align with the specified SNR performance.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS5481 family of high-performance ADCs from Texas Instruments. It shares core architectural similarities with variants like the ADS5481IRGCR and ADS5481IRGCT, differing primarily in packaging and shipping quantities. The family is designed for applications demanding high linearity and wide dynamic range in a single-channel configuration.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-to-pin replacements within the same family include the ADS5481IRGCR and ADS5481IRGCT. Cross-vendor alternatives such as the AD9265 or AD9246 may require significant schematic and layout modifications due to differences in interface protocols and power supply requirements.
