MAX197ACWI Equivalent & Substitute Parts

Part Overview

The MAX197ACWI is a 12-bit Data Acquisition System (DAS) integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. This component features 8 channels, a 100 kHz sampling rate, and parallel data interface in a 28-SOIC surface mount package. The MAX197ACWI is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, design updates, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX197ACWI is determined by matching the following critical parameters:

• Resolution (Bits): 12 bits
• Number of Channels: 8 channels
• Sampling Rate (Per Second): 100 kHz
• Data Interface: Parallel
• Voltage Supply Source: Single Supply
• Operating Temperature Range: 0°C to 70°C
• Package / Case: 28-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

The MAX197ACWI+ meets all these criteria and is classified as a direct manufacturer equivalent. The primary distinction between the main part and its substitute is product status and compliance certification, not functional or electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The MAX197ACWI+ is the direct functional equivalent of the MAX197ACWI. Both components share identical electrical specifications, channel count, resolution, sampling rate, data interface, and package configuration. The MAX197ACWI+ is preferred for new designs and procurement due to its active product status and ROHS3 compliance certification. The obsolete MAX197ACWI should be replaced with MAX197ACWI+ in applications requiring regulatory compliance with modern environmental standards. Both components maintain identical moisture sensitivity levels and export classifications.

Frequently Asked Questions (FAQ)

Q: Can MAX197ACWI+ directly replace MAX197ACWI in existing designs?

A: Yes. Both components are electrically and mechanically identical. The MAX197ACWI+ uses the same 28-SOIC package, pin configuration, and functional specifications. No circuit modifications are required for substitution.

Q: What is the primary difference between MAX197ACWI and MAX197ACWI+?

A: The MAX197ACWI+ is the active production variant with ROHS3 compliance certification. The MAX197ACWI is classified as obsolete. Functionally, both components deliver identical performance across all specified parameters.

Q: Are there supply voltage differences between these parts?

A: The MAX197ACWI+ specifies a supply voltage range of 4.75V to 5.25V. The MAX197ACWI does not include explicit voltage specification in available documentation. Both operate as single supply devices within the 0°C to 70°C temperature range.

Q: Is the 28-SOIC package identical for both parts?

A: Yes. Both MAX197ACWI and MAX197ACWI+ use the 28-SOIC package with 0.295" width and 7.50mm body width. PCB footprints and assembly processes are identical.

Q: What is the moisture sensitivity level for these components?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there export or regulatory restrictions on these parts?

A: Both components are classified under ECCN EAR99 and HTSUS 8542.39.0001. REACH status is unaffected for both variants. The MAX197ACWI+ carries ROHS3 compliance certification.
