ADS62P49IRGCT

Analog To Digital Converters (ADC) Overview

The ADS62P49IRGCT is a dual-channel, 14-bit analog-to-digital converter (ADC) from Texas Instruments. It operates at a sampling rate of 250 MSPS with a pipeline architecture. The device features differential inputs and supports parallel or serial interfaces with LVDS output types. Power requirements include an analog supply of 3.15 V to 3.6 V and a digital supply of 1.7 V to 1.9 V. Key performance metrics include a signal-to-noise ratio (SNR) of 73 dB, an effective number of bits (ENOB) of 11.3 bits, and power dissipation of 1.15 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

• Dual-channel high-performance pipeline architecture for simultaneous signal acquisition
• Integrated clock generator providing follow-the-sampling clock outputs for downstream FPGA synchronization
• Flexible interface options supporting both parallel and serial data transmission modes

Analog To Digital Converters (ADC) Applications

• High-speed data acquisition systems requiring precise multi-channel conversion
• Test and measurement equipment utilizing fast ADC sampling rates
• Communication infrastructure components needing low-latency signal processing

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRGCT corresponds to the VQFN-64 package and reel/cut-tape availability. Confirm humidity sensitivity handling requirements during storage and assembly. Ensure the ordering documentation matches the exact part number to avoid confusion with similar ADS62P series variants that may have different resolutions or speeds.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel 14-bit resolution at 250 MSPS is required. Compare SNR and ENOB against system noise floor requirements. Evaluate the 1.15 W power dissipation against thermal management capabilities. Consider the integrated clock generator if FPGA timing alignment is a design priority over external clock distribution complexity.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS62P49 series, designed for applications demanding high linearity and speed. It shares the VQFN-64 footprint with other members of the family but differs in resolution and sampling speed compared to parts like the ADS62P19 or ADS62P23. The integration of a clock generator distinguishes it from simpler ADCs that require external clock buffers for proper system timing.

Analog To Digital Converters (ADC) Replacement Considerations

ADS62P49IRGCR serves as a tape-and-reel alternative to the cut-tape IRGCT variant. Other ADS62P series devices offer different resolutions or speeds but do not provide identical electrical specifications.
