ADC1001CCJ Equivalent & Substitute Parts

Part Overview

The ADC1001CCJ is a 10-bit Analog to Digital Converter manufactured by Texas Instruments, configured as a single-input SAR (Successive Approximation Register) architecture device in a 20-CDIP package. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and new design implementations. The part operates with internal voltage reference and parallel data interface, serving applications requiring moderate-resolution analog signal acquisition.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADC1001CCJ is determined by the following critical parameters:

• Resolution: 10-bit conversion capability
• Input Configuration: Single input channel
• Architecture: SAR-based analog to digital conversion
• Data Interface: Parallel output
• Reference: Internal voltage reference
• Package Compatibility: 20-pin DIP form factor (0.300" pitch, 7.62mm)
• Mounting: Through-hole technology
• Supply Voltage Range: Compatibility with 4.5V to 6.3V single supply or equivalent dual-supply operation

The AD573JNZ from Analog Devices Inc. qualifies as a substitute based on matching resolution (10-bit), single-input configuration, SAR architecture, parallel interface, internal reference, and compatible 20-pin DIP package. Both devices support through-hole mounting and operate within overlapping voltage supply ranges.

Parameter Comparison

Engineering Selection Recommendations

The AD573JNZ is the designated substitute for the obsolete ADC1001CCJ. Selection of this substitute is supported by the following factors:

• Product Status: The AD573JNZ maintains active product status, ensuring continued availability and manufacturer support, whereas the ADC1001CCJ is obsolete.
• Regulatory Compliance: The AD573JNZ achieves ROHS3 compliance, meeting current environmental and regulatory requirements. The ADC1001CCJ is RoHS non-compliant.
• Functional Equivalence: Both devices share identical resolution (10-bit), input configuration (single channel), conversion architecture (SAR), data interface (parallel), and reference implementation (internal).
• Package Compatibility: Both devices utilize 20-pin DIP packages with 0.300" (7.62mm) pitch, supporting direct board-level substitution with through-hole mounting.

Frequently Asked Questions (FAQ)

Q: Can the AD573JNZ directly replace the ADC1001CCJ on existing PCBs?

A: Yes. Both devices use identical 20-pin DIP packages with 0.300" pitch. Pin compatibility and functional equivalence support direct substitution on through-hole mounted boards.

Q: What are the key differences between these two parts?

A: The primary differences are product status (AD573JNZ is active; ADC1001CCJ is obsolete), regulatory compliance (AD573JNZ is ROHS3 compliant; ADC1001CCJ is not), and input type (AD573JNZ is single-ended; ADC1001CCJ is differential). Both maintain 10-bit resolution, SAR architecture, parallel interface, and internal reference.

Q: Are the supply voltage ranges compatible?

A: The ADC1001CCJ operates at 4.5V to 6.3V. The AD573JNZ supports +4.5V to 7V and -12V to 16.5V dual-supply operation. Single-supply operation of the AD573JNZ within the 4.5V to 6.3V range is compatible with the original part's supply requirements.

Q: Does the input type difference (differential vs. single-ended) affect substitution?

A: Input type is a functional characteristic that must be evaluated within the context of the application circuit. The differential input of the ADC1001CCJ and single-ended input of the AD573JNZ require circuit-level assessment to confirm compatibility with signal conditioning and biasing schemes.

Q: What is the inventory status of these parts?

A: The ADC1001CCJ has 2100 pieces in stock (new original). The AD573JNZ has 1206 pieces in stock (new original, tube packaging).
