Analog To Digital Converters (ADC) Applications

• Process and machine control systems
• Consumer electronics applications
• Automotive data acquisition

Analog To Digital Converters (ADC) Procurement Notes

Verify the component status as LIFEBUY, indicating discontinuation with a limited lifetime-buy period available. Confirm package specifications match the required 28-pin PDIP form factor. Ensure compliance with environmental standards by checking for the /NOPB suffix if RoHS compliance is mandatory for the design.

Analog To Digital Converters (ADC) Selection Notes

Select this component for designs requiring low-speed, cost-effective 8-bit conversion with multiple analog inputs. Verify that the 10 ksps sampling rate meets system bandwidth requirements. Ensure the 4.5 V to 6.0 V supply voltage range aligns with the target power rail. Consider the LIFEBUY status for long-term production planning.

Analog To Digital Converters (ADC) Part Context

The ADC0808 serves as the monolithic CMOS equivalent to the MM74C949. It shares functional similarities with the ADC0809 but lacks the dedicated EOC output pin found in the latter. This device represents a standard solution for legacy microprocessor-based data acquisition architectures requiring integrated multiplexing.

Analog To Digital Converters (ADC) Replacement Considerations

Public confirmed substitute part numbers are not provided in the source documentation. Designers should consult Texas Instruments for current alternative recommendations due to the LIFEBUY status.
