ADS4245IRGCT

Analog To Digital Converters (ADC) Overview

The ADS4245IRGCT is a dual-channel, 14-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates at a sampling rate of 125 MSPS with a pipeline architecture and differential input type. The device utilizes a single 1.8 V supply for both analog and digital domains, achieving a power dissipation of 200 mW. Key performance metrics include a signal-to-noise ratio (SNR) of 71.4 dB. It features parallel CMOS and LVDS output interfaces and is housed in a VQFN-64 package. The component supports an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel configuration supporting simultaneous high-speed data acquisition
• Ultralow-power design enabled by a single 1.8 V supply architecture
• Integrated internal reference eliminating external components
• Flexible digital output interface supporting both CMOS and LVDS modes

Analog To Digital Converters (ADC) Applications

• Software-defined radio systems
• Wideband communication infrastructure
• Test and measurement equipment requiring low power consumption

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IRGCT' to confirm the tape-and-reel packaging variant and industrial temperature rating. Ensure compatibility with existing PCB footprints for the VQFN-64 PowerPAD package. Confirm that the 1.8 V supply requirements align with the system design before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance between 14-bit resolution and ultralow power consumption is required for dual-channel applications. Compare against the ADS4246 for higher sampling rates or the ADS4242 for lower speeds. Verify that the 125 MSPS throughput meets the Nyquist criteria for the target signal bandwidth.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS42xx family of ultralow-power ADCs from Texas Instruments. It shares the VQFN-64 package and 1.8 V supply architecture with siblings like the ADS4242 and ADS4246. The family is designed for multi-carrier, broadband communications where power efficiency is critical.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS4246IRGCT offers a higher sampling rate of 160 MSPS within the same package. The ADS4242IRGCT provides a lower sampling rate of 65 MSPS. Both are direct pin-compatible alternatives within the same series.
