ADC34J22IRGZR

Analog To Digital Converters (ADC) Overview

The ADC34J22IRGZR is a quad-channel, 12-bit analog-to-digital converter manufactured by Texas Instruments. It operates at a sampling rate of 50 MSPS and utilizes a pipeline architecture. The device features differential inputs and supports JESD204B digital interfaces. It functions within an analog and digital supply voltage range of 1.7V to 1.9V. Key performance metrics include an Effective Number of Bits (ENOB) of 11.5 bits, a Spurious-Free Dynamic Range (SFDR) of 100 dB, and a Signal-to-Noise and Distortion Ratio (SINAD) of 70.7 dB. Power consumption is specified at 491 mW. The component is housed in a 48-VQFN package with exposed pad and supports an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates four independent high-speed pipeline ADC channels for simultaneous signal acquisition.
• Supports JESD204B standard interface for simplified digital connectivity and reduced pin count.
• Features synchronous sampling capability across all four channels to maintain phase coherence.
• Designed for low power operation suitable for battery-powered or thermally constrained applications.

Analog To Digital Converters (ADC) Applications

• Software Defined Radio (SDR) systems requiring multi-channel reception.

• Medical imaging systems such as ultrasound scanners needing synchronized channel data.
• Industrial automation controllers processing multiple sensor inputs simultaneously.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRGZR against official Texas Instruments documentation to confirm tape-and-reel packaging and industrial temperature grade. Ensure compatibility with JESD204B link configurations during procurement planning. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when four synchronized 12-bit channels are required at 50 MSPS. Compare ENOB and SFDR specifications against system noise floor requirements. Verify that the 1.8V nominal supply voltage aligns with available board power rails. Confirm that the VQFN-48 footprint matches the PCB layout constraints and thermal management strategy.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADC34Jxx family of quad-channel converters from Texas Instruments. It shares architectural similarities with other members like the ADC34J23 and ADC34J24, differing primarily in resolution and speed variants. The IRGZR designation indicates the industrial temperature range and reel packaging format within this product line.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include ADC34J22IRGZT for tray packaging. For different resolutions or speeds, consider ADC34J23 or ADC34J24 variants if pinout and interface compatibility allow. Verify mechanical outline drawings and electrical characteristics before substituting.
