ADS6444IRGCT

Analog To Digital Converters (ADC) Overview

The ADS6444IRGCT is a quad-channel, 14-bit analog-to-digital converter (ADC) from Texas Instruments. It operates at a sampling rate of 105 MS/s with a pipeline architecture and differential input type. The device utilizes an I2C interface for control and features LVDS digital outputs. It requires a 3.3 V analog supply and a 3 V to 3.6 V digital supply. Key performance metrics include a signal-to-noise ratio (SNR) of 73.8 dB, an effective number of bits (ENOB) of 11.7 bits, and a full power bandwidth supporting high-speed data acquisition. It is housed in a VQFN-64 package.

Analog To Digital Converters (ADC) Feature Summary

• Quad-channel architecture providing four independent 14-bit ADCs within a single component
• High-performance pipeline structure optimized for wideband signal processing applications
• Integrated low-voltage differential signaling (LVDS) output drivers for reliable high-speed data transmission
• I2C serial interface enabling simplified configuration and monitoring without additional parallel control lines

Analog To Digital Converters (ADC) Applications

• Software-defined radio systems requiring multi-channel signal digitization
• Wideband instrumentation and test equipment
• Medical imaging systems such as ultrasound scanners
• Military radar and electronic warfare receivers

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix against official documentation, as the IRGCR variant is listed as obsolete while the IRGCT may have different packaging or availability status. Confirm RoHS compliance and humidity sensitivity ratings prior to procurement. Ensure the source document explicitly identifies the manufacturer as Texas Instruments and matches the exact part number to avoid counterfeit components.

Analog To Digital Converters (ADC) Selection Notes

Select this component when four synchronized 14-bit channels are required at 105 MS/s. Compare SNR and ENOB values against system dynamic range requirements. Verify that the I2C interface meets system control needs rather than parallel configuration. Check power supply compatibility with available 3.3 V and 3 V rails. Consider thermal dissipation capabilities within the VQFN-64 package for the target application environment.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS64xx series of high-speed analog-to-digital converters. It shares the VQFN-64 footprint and pipeline architecture with other members of the family but differs in channel count and resolution. The ADS6444 specifically targets applications needing multiple simultaneous conversion channels without increasing board space significantly compared to single-channel solutions.
