Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADC0848CCVX is determined by strict equivalence across the following critical parameters:

• Resolution: 8-bit conversion capability
• Sampling Rate: 25 kSPS minimum performance
• Input Configuration: Support for 4/8 channel multiplexed input with differential, pseudo-differential, and single-ended modes
• Data Interface: Parallel output protocol
• Architecture: SAR-based conversion
• Reference Input: External voltage reference requirement
• Supply Voltage Ranges: Analog and digital supplies within 4.5V ~ 6V specification
• Operating Temperature: -40°C ~ 85°C range
• Package: 28-PLCC surface mount form factor with identical pin pitch and dimensions

Only parts meeting all these criteria without deviation qualify as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The ADC0848CCVX/NOPB qualifies as a direct functional substitute for the obsolete ADC0848CCVX. The substitute part maintains active product status with National Semiconductor, ensuring continued availability and supply chain stability. Both parts share identical electrical specifications, pin configurations, and package dimensions, enabling direct replacement without circuit modification.

Selection between the main part and substitute should be based on:

• Availability: The substitute part (ADC0848CCVX/NOPB) is currently in active production status, whereas the main part is obsolete
• Supply Chain: Current inventory levels and lead times from authorized distributors
• Compliance Requirements: Both parts carry identical ECCN and HTSUS classifications, with no differential regulatory impact
• Application Continuity: For legacy system maintenance, either part provides equivalent performance; for new designs, the active substitute is preferred

Frequently Asked Questions (FAQ)

Q: Can ADC0848CCVX/NOPB be used as a direct replacement for ADC0848CCVX?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The substitute maintains the same 8-bit resolution, 25 kSPS sampling rate, 4/8 input channel configuration, parallel interface, and 28-PLCC package. No circuit redesign or firmware modification is required.

Q: What is the difference between the main part and the substitute?

A: The primary difference is manufacturer designation and product status. ADC0848CCVX is manufactured by Texas Instruments and classified as obsolete. ADC0848CCVX/NOPB is manufactured by National Semiconductor and maintains active product status. Electrical and functional specifications are identical.

Q: Are there any package or pinout differences?

A: No. Both parts use the 28-PLCC (11.51x11.51) surface mount package with identical pin assignments and J-Lead configuration. PCB footprints and assembly processes remain unchanged.

Q: What supply voltages are required?

A: Both analog and digital supply voltages must be within the 4.5V ~ 6V range. External voltage reference is required for both parts.

Q: Can these parts operate outside the -40°C ~ 85°C temperature range?

A: No. Both parts are specified for operation only within -40°C to 85°C. Applications requiring extended temperature ranges require alternative component selection.

Q: Are there any compliance or regulatory differences?

A: No. Both parts carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. RoHS and REACH compliance status should be verified with the specific supplier for current production lots.
