Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance and moisture sensitivity level (MSL 3) requirements for storage and handling. Ensure the specific suffix matches the required tape-and-reel packaging configuration for automated assembly processes.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 1MSPS sampling rate are required in a compact SOT-23-8 footprint. It serves as a drop-in replacement for AD7450A devices. Consider the external reference requirement and the specific operating temperature range of -40°C to +85°C for industrial environments.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ISL267450 series, which includes 10-bit (ISL267440) and 12-bit variants. The series is characterized by excellent linearity over supply and temperature variations. The AIHZ-T7A suffix specifically denotes the SOT-23-8 package with tape-and-reel shipping, distinguishing it from MSOP tube packages.

Analog To Digital Converters (ADC) Replacement Considerations

The datasheet explicitly states drop-in compatibility with the AD7440 and AD7450A. Verify pinout and electrical specifications against these equivalents before substitution. No other official substitutes are documented in the provided source material.
