ADS62P44IRGCT

Analog To Digital Converters (ADC) Overview

The ADS62P44IRGCT is a dual-channel, 14-bit analog-to-digital converter (ADC) from Texas Instruments. It operates at a sampling rate of 105 MSPS with a pipeline architecture. The device accepts differential analog inputs and provides LVDS digital outputs. It requires an analog supply voltage ranging from 3.15 V to 3.6 V and a digital supply voltage between 1.7 V and 1.9 V. Key performance metrics include a signal-to-noise ratio (SNR) of 72.8 dB, an effective number of bits (ENOB) of 11.4 bits, and a power dissipation of approximately 1.15 W. It functions within an industrial temperature range of -40°C to +85°C and is housed in a VQFN-64 package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRGCT against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration. Ensure that the ordering part number matches the exact temperature grade and package variant required for the design. Cross-reference the component marking with the official identification guide to prevent counterfeit substitution during assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a dual-channel solution with 14-bit resolution and 105 MSPS throughput is required. Compare SNR and SFDR specifications against single-channel alternatives if channel count flexibility is needed. Verify that the system power budget accommodates the specified analog and digital supply requirements while maintaining thermal limits within the VQFN-64 footprint.

Analog To Digital Converters (ADC) Part Context

This model belongs to the ADS62Pxx family of high-performance ADCs designed for demanding RF applications. It shares the same VQFN-64 package and core architecture with variants like the ADS62P49 and ADS62P42, differing primarily in resolution and sampling speed. The series emphasizes low power consumption relative to its performance class, making it suitable for multi-carrier systems.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible substitutes within the same family include the ADS62P49IRGCT and ADS62P42IRGCT. Verify that the alternative part's sampling rate and resolution meet the application requirements before substitution.
