ADC3443IRTQR

Analog To Digital Converters (ADC) Overview

The ADC3443IRTQR is a quad-channel, 12-bit analog-to-digital converter manufactured by Texas Instruments. It operates at a sampling rate of 80 MSPS and utilizes a pipeline architecture. The device features differential analog inputs and supports LVDS serial data output interfaces. It functions within an analog supply voltage range of 1.7 V to 1.9 V and a digital supply voltage range of 1.7 V to 1.9 V. The component is housed in a 64-pin TQFP package with exposed pad and is rated for operation between -40°C and +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RQR' against the manufacturer's official datasheet to confirm pinout and packaging details. Ensure that the required power supply voltages match the specified 1.7 V to 1.9 V ranges for both analog and digital domains before integration into the design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when four independent high-speed channels are required within a single package. Consider the 12-bit resolution and 80 MSPS speed as primary constraints. Evaluate the LVDS interface requirements against the downstream processing logic to ensure signal integrity and timing alignment.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC34xx family of high-speed data converters from Texas Instruments. It shares architectural similarities with the ADC3422 and ADC3442 but offers four channels instead of two. The family is designed for applications requiring multiple synchronized sampling paths.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC3442IRTQR serves as a dual-channel alternative within the same family. For higher channel counts, the ADC3460 series may be considered. Verify pin compatibility and software configuration differences before substituting.
