Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADC0809CCV is determined by strict equivalence across the following critical parameters:

• Resolution and Sampling: 8-bit resolution with 10 kHz sampling rate
• Input Configuration: 8 single-ended analog inputs with multiplexer and sample-hold architecture
• Interface Protocol: Parallel digital output
• Converter Architecture: Single SAR converter with 1:1 sample-hold to ADC ratio
• Supply Voltage Compatibility: Dual supply rails (analog and digital) operating within 4.5V to 6.5V range
• Reference Configuration: External voltage reference requirement
• Physical Form Factor: 28-PLCC surface mount package with J-lead configuration
• Temperature Range: Extended industrial temperature operation from -40°C to 85°C

The ADC0808CCV/NOPB qualifies as a parametric equivalent based on identical electrical specifications, pin configuration, and package form factor. Differences in product status and compliance certifications do not affect functional interchangeability within the specified parameter set.

Engineering Selection Recommendations

The ADC0808CCV/NOPB serves as the direct parametric equivalent for the obsolete ADC0809CCV. Selection between these parts should be based on the following factors:

Product Status Consideration: The ADC0809CCV is classified as obsolete with no ongoing manufacturing or support. The ADC0808CCV/NOPB carries Last Time Buy status, indicating limited future availability. For new designs or long-term production requirements, alternative sourcing strategies should be evaluated.

Compliance and Certification: The ADC0808CCV/NOPB provides ROHS3 compliance, whereas the ADC0809CCV is RoHS non-compliant. For applications subject to RoHS directives or customer compliance requirements, the ADC0808CCV/NOPB is the appropriate selection. Both parts maintain REACH Unaffected and EAR99 export classification status.

Packaging and Handling: Both parts are supplied in 28-PLCC surface mount packages with identical moisture sensitivity levels (2A, 4 weeks). No modifications to PCB layout, assembly processes, or handling procedures are required for substitution.

Functional Equivalence: Electrical performance, pin configuration, and operational characteristics are identical across all specified parameters. Direct pin-for-pin replacement is supported without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the ADC0808CCV/NOPB be used as a direct replacement for the ADC0809CCV in existing designs?

A: Yes. The ADC0808CCV/NOPB is functionally equivalent across all electrical and mechanical parameters. Pin configuration, package form factor, and operational specifications are identical. No circuit modifications are required.

Q: What is the difference between the ADC0809CCV and ADC0808CCV/NOPB?

A: The primary differences are product status and compliance certification. The ADC0809CCV is obsolete and RoHS non-compliant. The ADC0808CCV/NOPB is Last Time Buy status and ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the 28-PLCC (11.51x11.51) surface mount package with J-lead configuration. Pinout and package dimensions are identical.

Q: What does "Last Time Buy" status mean for the ADC0808CCV/NOPB?

A: Last Time Buy indicates that the manufacturer has announced end-of-life for this part. Existing inventory may be available for a limited period, but no new production is planned. For applications requiring long-term component availability, alternative parts or design strategies should be considered.

Q: Are both parts suitable for industrial temperature range applications?

A: Yes. Both the ADC0809CCV and ADC0808CCV/NOPB operate across the extended temperature range of -40°C to 85°C, supporting industrial and harsh environment applications.

Q: What are the moisture sensitivity requirements for handling these parts?

A: Both parts carry MSL 2A (4 Weeks) classification. Components must be stored in controlled humidity environments and used within four weeks of exposure to ambient conditions exceeding 30% relative humidity.
