ADS6445IRGCR

Analog To Digital Converters (ADC) Overview

The ADS6445IRGCR is a quad-channel, 14-bit analog-to-digital converter (ADC) from Texas Instruments. It supports sampling rates up to 125 MSPS and features serial LVDS outputs to minimize interface pin count within a compact 64-pin VQFN package. The device includes an internal reference voltage source and offers programmable gain options, including a 3.5 dB coarse gain setting to improve spurious-free dynamic range (SFDR). It operates on 3.3V analog and digital supplies, with a specified operating temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Quad-channel architecture with high integration density in a small form factor
• Serial LVDS data output interface for simplified receiver design
• Internal reference voltage source eliminating the need for external decoupling
• Programmable gain structure supporting coarse and fine adjustments

Analog To Digital Converters (ADC) Applications

• Wireless infrastructure base stations
• Software-defined radio systems
• Instrumentation and test equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer verification. Confirm that the specific suffix matches the required performance grade and packaging format. Ensure storage conditions adhere to moisture sensitivity level requirements prior to soldering. Validate that the revision level aligns with current design specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a four-channel solution with 14-bit resolution and high-speed serial output is required. Compare against the ADS6444 if lower sampling rates are sufficient, or the ADS6445MRGCTEP for extended industrial temperature ranges. Evaluate board space constraints against the 9 mm x 9 mm QFN footprint and verify clock input compatibility with available signal sources.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS644X family of high-performance ADCs designed for dense multi-channel applications. It shares functional similarities with the ADS6444 but typically offers higher maximum sampling speeds. The series is characterized by its ability to reduce system complexity through serialized data outputs while maintaining high linearity and dynamic range performance.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS6444IRGCR is a functionally compatible alternative within the same package, though it may operate at a reduced maximum sampling rate. Verify that the application timing requirements are met by the substitute part's specifications before implementation.
