ADC34J44IRGZR

Analog To Digital Converters (ADC) Overview

The ADC34J44IRGZR is a quad-channel, 14-bit analog-to-digital converter manufactured by Texas Instruments. It operates at a sampling rate of 125 MSPS using a pipeline architecture. The device features differential inputs and supports both external and internal reference configurations. Power supply requirements include 1.8 V for both analog and digital domains. Key performance metrics include 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 a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required packaging options. Confirm that the voltage and pinout specifications match the target system design before procurement. Check for any recent lifecycle notices or obsolescence warnings directly from Texas Instruments documentation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when four synchronized 14-bit channels are required at 125 MSPS. Compare power dissipation and SFDR requirements against alternative models in the ADC34Jxx family. Ensure the PCB layout supports the VQFN-48 package thermal requirements and high-speed differential signaling constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC34J44 series, which focuses on high-performance, low-power quadruple channel conversion. It shares the VQFN-48 footprint with other members like the ADC34J24 and ADC34J45, though sampling rates and resolution may vary across the family. The IRGZR suffix indicates the tape and reel packaging variant.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitutes include ADC34J44IRGZT for cut-tape packaging variations within the same electrical specification.
