MAX172AENG+ Equivalent & Substitute Parts

Part Overview

The MAX172AENG+ is a 12-bit analog-to-digital converter manufactured by Analog Devices Inc./Maxim Integrated, designed for single-ended input data acquisition applications. This SAR (Successive Approximation Register) architecture device operates at a 100 kHz sampling rate with parallel data interface output. The part is currently in active production status and widely used in industrial measurement, instrumentation, and embedded systems requiring moderate-resolution analog conversion. Identifying equivalent and substitute parts is essential for supply chain continuity, design flexibility, and long-term product support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX172AENG+ is determined by strict equivalence across the following critical parameters:

• Resolution: 12-bit conversion capability
• Sampling Rate: 100 kHz minimum performance
• Input Configuration: Single-ended input topology
• Architecture: SAR-based analog-to-digital conversion
• Data Interface: Parallel output format
• Reference Type: Internal voltage reference
• Supply Voltage Compatibility: Support for 5V, -12V, and -15V analog and digital supplies
• Package: 24-DIP through-hole form factor
• Operating Temperature: -40°C to 85°C range
• Compliance: ROHS3 and REACH compliance status

Only parts meeting all these parameters qualify as direct substitutes. No functional or performance degradation is acceptable in substitute selection.

Parameter Comparison

Engineering Selection Recommendations

The MAX172AENG+ maintains active product status with full ROHS3 compliance and REACH unaffected classification, ensuring regulatory compliance for current and future applications. The part's MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling. Selection of equivalent parts should prioritize components with identical active product status, matching compliance certifications, and verified supply chain availability. Through-hole 24-DIP packaging remains suitable for legacy designs and applications requiring manual assembly or rework accessibility. The internal voltage reference eliminates external reference component requirements, simplifying circuit design and reducing board space.

Frequently Asked Questions (FAQ)

Q: What makes a part a direct substitute for the MAX172AENG+? A: A direct substitute must match all critical parameters: 12-bit resolution, 100 kHz sampling rate, single-ended input, SAR architecture, parallel data interface, internal reference, multi-supply voltage support (5V, -12V, -15V), 24-DIP package, -40°C to 85°C operating range, and ROHS3 compliance.

Q: Can I use a different package type as a substitute? A: No. The 24-DIP through-hole package is a critical specification. Different package types (such as SOIC or QFP variants) are not interchangeable without PCB redesign and are classified as alternative designs rather than direct substitutes.

Q: Is the MAX172AENG+ suitable for new designs? A: Yes. The part maintains active product status with full regulatory compliance (ROHS3, REACH unaffected), making it appropriate for both legacy support and new product development.

Q: What is the significance of the internal voltage reference? A: The internal reference eliminates the need for external reference circuitry, reducing component count, simplifying PCB layout, and improving system reliability by reducing external component dependencies.

Q: Are there any supply voltage restrictions? A: The MAX172AENG+ supports multiple supply configurations: 5V, -12V, and -15V for both analog and digital supplies. Circuit design must accommodate the specific voltage rails required by the application.

Q: What does MSL 1 (Unlimited) mean for component handling? A: MSL 1 indicates no moisture sensitivity level restrictions. The component can be stored indefinitely without desiccant packaging or time-limited shelf life constraints, simplifying inventory management and logistics.
