Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CIMMX' against the official Texas Instruments datasheet to confirm package type and temperature grade. Ensure the ordering part number matches the exact pinout and electrical specifications required for your design. Cross-reference with authorized distributors to confirm current availability and authenticity. Check for any recent revisions or obsolescence notices regarding this specific variant.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-resolution 16-bit conversion is required at moderate speeds up to 250 kSPS. It is suitable for designs needing differential inputs to reject common-mode noise while maintaining low power consumption. Consider the dual-supply requirement if the system logic operates at a different voltage than the analog front end. Evaluate the TSSOP-14 package constraints against PCB space limitations.
