MAX197AEAI Data Acquisition IC - Equivalent & Substitute Parts

Part Overview

The MAX197AEAI 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-SSOP surface mount package. The MAX197AEAI is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX197AEAI is determined by strict equivalence across the following critical parameters:

• Channel Count: 8 channels (fixed requirement)
• Resolution: 12 bits (fixed requirement)
• Sampling Rate: 100 kHz (fixed requirement)
• Data Interface: Parallel (fixed requirement)
• Package: 28-SSOP with identical physical dimensions (fixed requirement)
• Voltage Supply Configuration: Single supply operation (fixed requirement)
• Operating Temperature Range: -40°C to 85°C (fixed requirement)

The MAX197AEAI+ meets all these criteria and is classified as a direct equivalent. The primary distinction is product status: the original MAX197AEAI is obsolete, while the MAX197AEAI+ is active and available in production quantities.

Parameter Comparison

Engineering Selection Recommendations

The MAX197AEAI+ is the direct active equivalent for the obsolete MAX197AEAI. Selection of the MAX197AEAI+ is appropriate for:

• New product designs requiring 12-bit, 8-channel data acquisition with 100 kHz sampling
• Replacement of obsolete MAX197AEAI components in existing production lines
• Applications requiring ROHS3 compliance, where the MAX197AEAI+ meets current regulatory standards while the original does not
• Designs where supply voltage is constrained to the 4.75V to 5.25V range specified for the MAX197AEAI+

Both parts share identical functional specifications, package geometry, and thermal operating range. The transition from MAX197AEAI to MAX197AEAI+ introduces improved regulatory compliance without functional or mechanical changes.

Frequently Asked Questions (FAQ)

Q: Can the MAX197AEAI+ be used as a direct replacement for the MAX197AEAI in existing designs?

A: Yes. The MAX197AEAI+ is functionally and mechanically equivalent. Both parts feature 8 channels, 12-bit resolution, 100 kHz sampling rate, parallel data interface, and identical 28-SSOP packaging. No circuit modifications are required.

Q: What is the primary difference between these two parts?

A: The MAX197AEAI is classified as obsolete with no active manufacturing. The MAX197AEAI+ is an active product with current production availability. Additionally, the MAX197AEAI+ meets ROHS3 compliance standards, while the original does not.

Q: Are the supply voltage specifications identical?

A: The MAX197AEAI+ specifies a supply voltage range of 4.75V to 5.25V. The original MAX197AEAI does not include explicit voltage specifications in the provided data. Designs using the MAX197AEAI+ should confirm operation within the stated 4.75V to 5.25V range.

Q: Is the 28-SSOP package identical between both parts?

A: Yes. Both parts use the 28-SSOP package with 0.209" width and 5.30mm physical dimensions. PCB footprints and assembly processes are identical.

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

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.

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

A: Both parts are classified under ECCN EAR99 and HTSUS code 8542.39.0001. Both have REACH Unaffected status. Consult applicable export regulations for your jurisdiction.
