ADC3444IRTQR

Analog To Digital Converters (ADC) Overview

The ADC3444IRTQR is a quad-channel, 14-bit analog-to-digital converter manufactured by Texas Instruments. It utilizes a pipeline architecture and supports sampling rates from 25 MSPS to 125 MSPS. The device operates with 1.8 V analog and digital power supplies within an industrial temperature range of -40°C to +85°C. It is housed in a 56-pin QFN package (IRTQR suffix). Key performance metrics include an Effective Number of Bits (ENOB) of approximately 11.9 bits, a Spurious-Free Dynamic Range (SFDR) of 90 dB, and a Signal-to-Noise and Distortion Ratio (SINAD) of 73.4 dB at maximum sampling speeds.

Analog To Digital Converters (ADC) Feature Summary

• Quad-channel configuration for simultaneous multi-channel signal acquisition
• Low-power design optimized for energy-efficient operation
• High-speed pipeline architecture supporting up to 125 MSPS per channel

Analog To Digital Converters (ADC) Applications

• Software Defined Radio (SDR)
• Wireless Local Area Network (WLAN) base stations
• Instrumentation and test equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix 'IRTQR' against the manufacturer's current datasheet to confirm package type and reel specifications. Ensure compatibility with 1.8V supply requirements and JESD204B interface standards during system integration planning.

Analog To Digital Converters (ADC) Selection Notes

Select this component when four independent high-resolution channels are required at sampling rates up to 125 MSPS. Compare SFDR and SINAD specifications against application bandwidth needs. Verify that the 56-QFN footprint fits the PCB layout constraints and thermal management requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC344x family of quad-channel converters. It shares architectural similarities with the ADC3424 (12-bit) and ADC3443 (single-channel), offering higher resolution than the 12-bit variants while maintaining low power consumption typical of the series.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC3444IRTQT is a tape-and-reel alternative to the IRTQR variant. Both share identical electrical characteristics and pinouts; selection depends on preferred packaging format.
