Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm that the component meets RoHS compliance standards as listed in official specifications. Ensure compatibility with the ADS6245EVM development kit if evaluation is required. Check humidity sensitivity handling requirements during storage and assembly processes to maintain device reliability.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring dual-channel 14-bit resolution at speeds up to 125 MSPS. Consider the 1.2 W power dissipation and 3.3 V/3 V supply requirements for thermal management. The serial LVDS output reduces pin count compared to parallel interfaces. Evaluate the 73.7 dB SNR against system noise floor requirements to ensure adequate dynamic range for the intended signal processing tasks.

Analog To Digital Converters (ADC) Part Context

The ADS6245 belongs to Texas Instruments' high-performance ADC portfolio, designed for demanding signal acquisition tasks. It complements other devices like the ADS6128 and ADS41B25, offering higher resolution than 12-bit alternatives.
