Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm the transport media configuration. The IRGC25 designation indicates the industrial temperature range and QFN-64 package type. Ensure that the procurement source provides valid production data consistent with the SBAS533C datasheet specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring low power consumption alongside high dynamic performance in multi-carrier environments. The ADS4225 is optimized for wide-bandwidth communications. Designers must account for the 1.8V supply requirement and ensure proper termination for the selected digital output interface.

Analog To Digital Converters (ADC) Part Context

The ADS4225 belongs to the ADS42xx family of ultralow-power ADCs, which are low-speed variants of the ADS424x series. This family utilizes innovative design techniques to achieve high performance while minimizing power usage. The device is pin-compatible with previous generations like the ADS62P49, facilitating migration, though supply voltage and common-mode requirements differ significantly.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS4222 serves as a lower-speed variant within the same family, supporting up to 65 MSPS. The ADS4226 offers higher speed capability up to 160 MSPS. Both share the same package and pinout but require verification of power and performance specifications relative to system requirements.
