Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CIVT' against the manufacturer's official datasheet to confirm pinout compatibility and temperature grade. Ensure the source document explicitly lists this part number as active or obsolete to determine availability status before procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance between moderate resolution and speed is required for low-power applications. Compare input impedance and noise specifications against alternative SAR ADCs if signal conditioning complexity must be minimized. Verify that the 16-lead TSSOP package fits the target PCB layout constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC1218x family of low-power, 12-bit ADCs from National Semiconductor. It shares architectural similarities with other members like the ADC12180 but differs in package options and specific electrical characteristics defined by the CIVT suffix.

Analog To Digital Converters (ADC) Replacement Considerations

Check for direct pin-to-pin replacements within the same family, such as the ADC12180CIVT, ensuring functional equivalence in reference voltage and interface timing. Cross-reference with newer generations from Texas Instruments following the acquisition.
