MAX172ACNG Equivalent & Substitute Parts

Part Overview

The MAX172ACNG is a 12-bit Analog to Digital Converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated, designed for single-ended input data acquisition applications. It features a Successive Approximation Register (SAR) architecture with a 100 kHz sampling rate and operates with dual supply voltages (5V, -12V, -15V). The device is packaged in a 24-pin DIP configuration for through-hole mounting.

The MAX172ACNG is classified as obsolete. Finding equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support legacy system maintenance or redesigns where this component is no longer readily available from primary sources.

Substitute Part Grouping Explanation

Substitution for the MAX172ACNG is determined by strict equivalence across the following critical parameters:

• Resolution: 12 bits
• Sampling Rate: 100 kHz
• Input Configuration: 1 single-ended input
• Data Interface: Parallel
• Architecture: SAR with internal reference
• Supply Voltages: 5V, -12V, -15V (both analog and digital)
• Operating Temperature: 0°C to 70°C
• Package: 24-DIP through-hole

The MAX172BCNG+ meets all these electrical and mechanical specifications, making it a parametric equivalent. The primary distinction between the main part and its substitute is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MAX172BCNG+ is the direct substitute for the MAX172ACNG. Both devices are electrically and mechanically identical across all functional parameters. The MAX172BCNG+ is preferred for new designs and legacy system maintenance because it maintains active product status with Analog Devices Inc./Maxim Integrated and carries ROHS3 compliance certification, whereas the MAX172ACNG is obsolete and RoHS non-compliant.

For applications requiring strict adherence to RoHS3 and REACH compliance standards, the MAX172BCNG+ is the appropriate selection. Both devices share identical moisture sensitivity levels and ECCN/HTSUS classifications, ensuring no additional regulatory or supply chain complications during substitution.

Frequently Asked Questions (FAQ)

Q: Can the MAX172BCNG+ directly replace the MAX172ACNG in existing designs?

A: Yes. The MAX172BCNG+ is a parametric equivalent with identical electrical specifications, sampling rate, resolution, input configuration, supply voltage requirements, and 24-DIP package dimensions. No circuit modifications are required for direct substitution.

Q: What is the primary advantage of using MAX172BCNG+ over MAX172ACNG?

A: The MAX172BCNG+ is an active product with ROHS3 compliance certification, whereas the MAX172ACNG is obsolete and RoHS non-compliant. This ensures long-term availability and regulatory compliance for new applications or system redesigns.

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

A: No. Both devices use the 24-DIP (0.300", 7.62mm) package with identical through-hole mounting specifications. Pinout and mechanical dimensions are identical.

Q: Do both parts require the same supply voltage configuration?

A: Yes. Both the MAX172ACNG and MAX172BCNG+ require identical dual supply voltages: 5V, -12V, and -15V for both analog and digital supplies.

Q: Is the MAX172BCNG+ available in different packaging options?

A: The MAX172BCNG+ is supplied in tube packaging, whereas the MAX172ACNG packaging specification was not provided. Both maintain the same 24-DIP component form factor for circuit board integration.
