ADS4222IRGCT

Analog To Digital Converters (ADC) Overview

The ADS4222IRGCT is a dual-channel, 12-bit analog-to-digital converter (ADC) from Texas Instruments. It operates at a sampling rate of 65 MSPS with a pipeline architecture. The device accepts differential analog inputs and provides parallel digital outputs. It functions on a single 1.8 V supply for both analog and digital domains. Key performance metrics include a signal-to-noise ratio (SNR) of 70.8 dB and an effective number of bits (ENOB) of 10.3 bits. The component is housed in a 64-pin VQFN package and supports an industrial operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel configuration enables simultaneous conversion of two independent signals within a single integrated circuit.
• Low-power design utilizes a single 1.8 V supply voltage to minimize energy consumption in portable applications.
• Integrated internal reference eliminates the need for external voltage references and associated decoupling capacitors.

Analog To Digital Converters (ADC) Applications

• Software-defined radio systems
• Wireless local area network (WLAN) infrastructure
• Point-to-point microwave communication links

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RGCT' to confirm the tape-and-reel packaging format and moisture sensitivity level. Ensure the order matches the exact pinout and thermal pad requirements for the VQFN-64 package. Cross-reference the datasheet revision date to confirm compatibility with current design specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance between moderate resolution and low power consumption is required. Compare against the ADS4225 or ADS4242 if higher sampling rates or bit resolutions are necessary. Evaluate the SNR and SFDR specifications against the dynamic range requirements of the target RF front-end application.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS42xx family of low-power, high-performance ADCs designed for multi-carrier broadband communications. It shares architectural similarities with the ADS4229 but offers different resolution and speed characteristics. The series is optimized for applications requiring efficient power usage without significant compromise in dynamic performance.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS4222IRGCR is available as a tube-packaged alternative with identical electrical characteristics. Verify that the change in packaging does not impact the reflow soldering profile or board layout constraints.
