ADC0820CCN Equivalent & Substitute Parts

Part Overview

The ADC0820CCN is an 8-bit flash analog-to-digital converter manufactured by Texas Instruments, housed in a 20-pin DIP package. This component features a single pseudo-differential or single-ended input with parallel data interface and external reference configuration. The ADC0820CCN is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ADC0820CCN is determined by strict equivalence across the following critical parameters: 8-bit resolution, single input channel, flash architecture, parallel data interface, external reference configuration, 4.5V to 8V dual supply voltage range, 20-DIP package format, and through-hole mounting. All identified substitutes maintain these core electrical and mechanical specifications.

The substitute parts are grouped into two categories based on input type compatibility:

Category 1 - Pseudo-Differential/Single Ended Input (Direct Functional Equivalent): ADC0820CCN+ maintains identical input type specification to the original part.

Category 2 - Single Ended Input Only (Functional Substitute with Input Type Variation): TLC0820ACN and TLC0820AIN operate as single-ended input variants, representing a functional constraint relative to the original pseudo-differential capability.

Engineering Selection Recommendations

ADC0820CCN+ (Recommended Primary Substitute): This part maintains identical electrical specifications and input type configuration to the original ADC0820CCN. It is actively manufactured and carries ROHS3 compliance certification. The improved moisture sensitivity level (MSL 1 vs. MSL 3) provides superior handling and storage characteristics. Selection of ADC0820CCN+ is appropriate for applications requiring direct functional equivalence with enhanced environmental compliance.

TLC0820ACN (Active Substitute - Standard Temperature Range): This Texas Instruments LinCMOS™ series component operates within the same 0°C to 70°C temperature range as the original part. It is actively manufactured and ROHS3 compliant. The input type is limited to single-ended operation, eliminating pseudo-differential capability. This part is suitable for applications where single-ended input configuration is acceptable and standard industrial temperature range is sufficient.

TLC0820AIN (Active Substitute - Extended Temperature Range): This Texas Instruments LinCMOS™ series component extends the operating temperature range to -40°C to 85°C, providing broader environmental coverage than the original specification. It is actively manufactured and ROHS3 compliant. Like TLC0820ACN, input type is limited to single-ended operation. Selection is appropriate for applications requiring extended temperature performance and single-ended input compatibility.

Frequently Asked Questions (FAQ)

Q: Can ADC0820CCN+ be used as a direct replacement for ADC0820CCN? A: Yes. ADC0820CCN+ maintains identical electrical specifications, input type configuration (pseudo-differential and single-ended), supply voltage range, package format, and pin assignment. It is the closest functional equivalent and is actively manufactured.

Q: What is the primary difference between ADC0820CCN+ and the TLC0820 series substitutes? A: The TLC0820ACN and TLC0820AIN variants support single-ended input only, whereas ADC0820CCN and ADC0820CCN+ support both pseudo-differential and single-ended input modes. If your application requires pseudo-differential input capability, ADC0820CCN+ is the appropriate selection.

Q: Are the TLC0820ACN and TLC0820AIN interchangeable? A: Both parts are electrically equivalent with identical input type, resolution, architecture, and supply specifications. The primary difference is operating temperature range: TLC0820ACN operates 0°C to 70°C, while TLC0820AIN operates -40°C to 85°C. Selection depends on the thermal requirements of your application.

Q: Does the package format remain consistent across all substitutes? A: Yes. All substitute parts use the 20-DIP (0.300", 7.62mm) package with through-hole mounting, ensuring direct PCB compatibility with the original ADC0820CCN design.

Q: What compliance improvements are provided by the substitute parts? A: All substitute parts are ROHS3 compliant, whereas the original ADC0820CCN is RoHS non-compliant. Additionally, ADC0820CCN+ and the TLC0820 series have improved or not-applicable moisture sensitivity levels, providing better handling and storage characteristics.

Q: Can I use a TLC0820 variant if my circuit uses pseudo-differential input configuration? A: No. The TLC0820ACN and TLC0820AIN support single-ended input only. If your design requires pseudo-differential input capability, ADC0820CCN+ is the required selection.

Q: What is the sampling rate specification for each part? A: The original ADC0820CCN and ADC0820CCN+ do not specify sampling rate in their datasheets. The TLC0820ACN and TLC0820AIN both specify a sampling rate of 392k samples per second.
