Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and lead-free status as per Texas Instruments standards. Confirm the package marking matches the HTQFP-64 physical dimensions. Ensure the ordering part number aligns with the required tape-and-reel quantity if applicable. Cross-reference the manufacturer date code to ensure recent production batches for optimal shelf life management.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 18-bit resolution and 1.25 MSPS throughput are required. Compare SNR and power consumption against alternative ADCs in the same family. Verify that the parallel interface timing meets the system clock constraints. Consider the thermal dissipation characteristics given the 520 mW typical power consumption in dense PCB layouts.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS1625 series of high-performance delta-sigma ADCs. It serves as a successor or variant to the ADS1625IPAPT, typically differing in packaging or compliance specifications. The series is designed for applications demanding high accuracy and low noise without complex external calibration circuits.

Analog To Digital Converters (ADC) Replacement Considerations

ADS1625IPAPT is a direct pin-compatible alternative within the same product family. Verify if the 'PAPT' suffix differs in reel packaging or RoHS status compared to the 'G4' designation. No other cross-model replacements are publicly confirmed for this specific part number.
