Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix 'SEL' against the manufacturer's official documentation to confirm package type and availability. Ensure compatibility with standard ±5V power supplies and CMOS logic levels for digital control signals before integration.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high accuracy independent of input source impedance. The 10 ppm/°C tempco specification makes it suitable for precision measurement systems where thermal stability is critical. Ensure external timing components support the required integration periods for desired noise rejection.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ALD500R series of precision integrating analog processors. The 'RA' designation indicates 17-bit resolution with a 10 ppm/°C temperature coefficient, distinguishing it from the 16-bit (ALD500R) and 18-bit (ALD500RAU) variants in the same family.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements include ALD500RA-20SE (20 ppm/°C) or ALD500RAU-10SE (18-bit resolution). Verify pinout compatibility and ensure the alternative part meets the specific 10 ppm/°C temperature coefficient requirement if thermal stability is mandatory.
