ADS4125IRGZR

Analog To Digital Converters (ADC) Overview

The ADS4125IRGZR is a single-channel, 12-bit analog-to-digital converter manufactured by Texas Instruments. It operates at a sampling rate of 125 MSPS using a pipeline architecture with an internal sample-and-hold configuration. The device accepts differential analog inputs and provides parallel LVDS digital outputs. It requires a single 1.7V to 1.9V supply for both analog and digital sections. Packaged in a 48-VQFN (7x7 mm) format with exposed pad, it supports surface-mount installation and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Ultralow-power consumption design optimized for battery-operated applications
• Integrated sample-and-hold circuitry simplifies front-end driver requirements
• Single-supply operation reduces system complexity and board space

Analog To Digital Converters (ADC) Applications

• Portable medical imaging systems
• Software-defined radio receivers
• Instrumentation and test equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the IRGZR suffix indicates tape-and-reel packaging rather than tube. Confirm RoHS3 compliance status through current manufacturer documentation. Check moisture sensitivity level handling requirements prior to assembly. Ensure ordering quantities align with standard reel sizes specified in the datasheet.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel 12-bit resolution is required at 125 MSPS. Compare power dissipation against higher-speed alternatives like the ADS6128 if performance needs increase. Verify input voltage ranges match the signal source specifications before integration into the design.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS41xx family of ultralow-power ADCs from Texas Instruments. It shares architectural similarities with the ADS4122 but offers different resolution and speed options. The device complements the broader portfolio designed for low-power data acquisition tasks.

Analog To Digital Converters (ADC) Replacement Considerations

ADS4125IRGZT serves as a tube-packaged alternative with identical electrical characteristics. ADS4122 variants offer similar speeds with different resolution options.
