ADS6425IRGCR

Analog To Digital Converters (ADC) Overview

The ADS6425IRGCR is a quad-channel, 12-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates at a sampling rate of 125 MSPS and utilizes a pipeline architecture. The device features differential analog inputs and LVDS digital outputs. It requires a 3.3 V analog supply and a 3 V to 3.6 V digital supply. Key performance metrics include a signal-to-noise ratio (SNR) of 71 dB, an effective number of bits (ENOB) of 11.5 bits, and power dissipation of 1.25 W. It functions within a temperature range of -40°C to +85°C and is housed in a VQFN-64 package.

Analog To Digital Converters (ADC) Feature Summary

• Integrates four independent 12-bit ADC channels for simultaneous multi-channel data acquisition.
• Supports high-speed digitization with a maximum sampling rate of 125 MSPS per channel.
• Incorporates an I2C interface for configuration control and status monitoring.
• Delivers high linearity performance with specified DNL and INL values.

Analog To Digital Converters (ADC) Applications

• Software-defined radio systems requiring multi-channel reception.
• Instrumentation and test equipment needing high-resolution digitization.
• Medical imaging systems utilizing multiple sensor arrays.
• Industrial automation controllers processing high-speed analog signals.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RGCR' against the manufacturer's official datasheet to confirm the reel packaging quantity and tape specifications. Ensure the component matches the required RoHS compliance standards for your assembly process. Cross-reference the active status and lead times directly with authorized distributors, as availability fluctuates. Confirm that the VQFN-64 footprint aligns with your PCB design guidelines before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this model when four synchronized 12-bit channels are required at 125 MSPS. Compare SNR and ENOB requirements against alternative TI models like the ADS6422 if lower speed suffices. Verify that the 3.3 V analog and 3 V digital supply rails match your system power architecture. Consider the VQFN-64 thermal characteristics and board space constraints relative to other package options in the ADS64xx family.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS64xx series of high-performance, low-power, quad-channel ADCs from Texas Instruments. It shares architectural similarities with the ADS6422 but offers higher sampling rates. The series is designed for applications demanding precise multi-channel data conversion with minimal external support circuitry. It complements TI's portfolio of mixed-signal solutions for communication and industrial markets.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS6422IRGCR serves as a compatible alternative within the same package, offering 65 MSPS operation. Verify pin compatibility and software register settings when substituting. Other family members may require level shifting or firmware updates due to differing interface configurations.
