ADC34J44IRGZT

Analog To Digital Converters (ADC) Overview

The ADC34J44IRGZT is a quad-channel, 14-bit analog-to-digital converter manufactured by Texas Instruments. It utilizes a pipeline architecture and supports sampling rates up to 125 MSPS. The device operates with both analog and digital supply voltages of 1.8 V. It features an effective number of bits (ENOB) of 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. Total power consumption is specified at 715 mW. The component is housed in a 48-pin VQFN package with exposed pad and functions within an industrial temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and reel specifications. Ensure compatibility with JESD204B interface requirements if used in serial configurations. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning. Cross-reference the part number with official Texas Instruments documentation to validate availability and lifecycle status.

Analog To Digital Converters (ADC) Selection Notes

Select this component when four synchronized 14-bit conversion channels are required at 125 MSPS. Compare against the ADC34J42 and ADC34J43 variants if fewer channels or different resolution/speed combinations are needed. Evaluate power budget constraints given the 715 mW total dissipation. Ensure the system design accommodates the 1.8 V supply requirement and the thermal management needs of the VQFN-48 package.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC34Jxx family of high-performance analog-to-digital converters designed for optical and wireless communication applications. It shares architectural similarities with the ADC34J42 and ADC34J43 models, differing primarily in channel count and resolution. The series is characterized by its integration of low-power pipeline technology and support for high-speed serial data output standards.
