ADC3422IRTQT

Analog To Digital Converters (ADC) Overview

The ADC3422IRTQT is a quad-channel, 12-bit analog-to-digital converter manufactured by Texas Instruments. It features four independent pipeline ADC cores operating at a sampling rate of 50 MSPS. The device accepts differential analog inputs and provides serial LVDS digital outputs. It operates on dual power supplies: analog and digital voltages range from 1.7V to 1.9V. The component is housed in a 56-pin VFQFN package with an exposed pad, measuring 8x8 mm. It supports external or internal voltage references and includes synchronous sampling capabilities across all channels.

Analog To Digital Converters (ADC) Feature Summary

• Integrates four independent 12-bit pipeline ADC cores for simultaneous multi-channel signal acquisition
• Supports high-speed data conversion with a maximum sampling rate of 50 MSPS per channel
• Features low-voltage operation with 1.7V to 1.9V supply requirements for analog and digital domains
• Provides serial LVDS output interface for efficient high-speed data transmission

Analog To Digital Converters (ADC) Applications

• Wireless base station receivers requiring multi-channel signal processing
• Instrumentation systems utilizing differential input architectures
• Software-defined radio platforms needing synchronized sampling

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix to confirm package type and reel specifications. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) prior to PCB assembly planning. Ensure the supplier provides valid traceability documentation for the Texas Instruments manufacturer part number. Check for any recent product change notices that may affect pinout or electrical characteristics.

Analog To Digital Converters (ADC) Selection Notes

Select this component when four synchronized 12-bit channels are required at 50 MSPS. Compare against the ADC3424IRTQT if a higher 125 MSPS sampling rate is necessary. Consider the ADC34J22IRGZT for applications requiring JESD204B interfaces instead of LVDS. Verify that the system design accommodates the 56-VFQFN thermal requirements and 1.8V nominal supply rails.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADC342x family of high-performance analog-to-digital converters. The family shares common architectural features including pipeline topology and low-voltage operation. Variants within the series differ primarily in sampling speed and interface standards. The ADC3422 specifically targets mid-speed applications requiring four-channel synchronization.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC3422IRTQ25 is listed as a direct replacement variant with identical electrical specifications but potentially different packaging options such as cut tape.
