ADS41B25IRGZT

Analog To Digital Converters (ADC) Overview

The ADS41B25IRGZT is a single-channel, 12-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates at a sampling rate of 125 MSPS and features an integrated analog input buffer. The device utilizes a pipeline architecture with differential inputs and supports parallel LVDS output interfaces. It functions on dual 1.8 V power supplies for both analog and digital sections. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 70.6 dB, an Effective Number of Bits (ENOB) of 10.9 bits, and a Spurious-Free Dynamic Range (SFDR) of 83 dB. Power consumption is rated at 265 mW. The component is housed in a 48-pin VQFN package and operates within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Instrumentation and test equipment
• Medical imaging systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the IRGZT variant matches the required thermal performance and moisture sensitivity level for the intended assembly process. Cross-reference the active status with official distribution channels to avoid obsolete stock.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 12-bit resolution is required at 125 MSPS with integrated buffering capabilities. Compare SNR and SFDR specifications against system dynamic range requirements. Ensure the parallel LVDS interface is compatible with the downstream FPGA or processor logic levels. Evaluate the 48-VQFN package constraints for PCB layout and thermal dissipation needs.

Analog To Digital Converters (ADC) Part Context

The ADS41B25 belongs to the ADS41xx family of ultralow-power ADCs from Texas Instruments. This series is designed for applications requiring high performance with reduced power consumption. It shares architectural similarities with other members like the ADS4125 and ADS4145 but differs in resolution and sampling speed. The integration of an analog buffer distinguishes it from earlier generations that required external drivers.

Analog To Digital Converters (ADC) Replacement Considerations

ADS4125IRGZT: Similar 12-bit, 125 MSPS architecture but lacks the integrated analog buffer. Verify if external buffering can be added to the design. ADS41B29IRGZT: Offers higher resolution options (14-bit) and potentially different sampling rates; check pinout compatibility and power requirements.
